What Is an Ultracapacitor and How Mach Do You Know About It?
Ⅰ. The difference between ultra capacitors and ordinary capacitors

The biggest difference between ultra capacitors and an ordinary capacitors is that it is an electrochemical physical component, but it does not undergo a chemical reaction itself. The storage capacity of a super capacitor is particularly large, reaching a farad-level capacitance.

Ⅱ. The working principle of ultra capacitors

How to increase the area of the bipolar plates? Ultra capacitors store energy by injecting electrolyte. Under the action of the electrode, the surface charge of the electrode will attract the opposite ions in the surrounding electrolyte solution, and these ions will attach to the surface of the electrode to form an electric double layer, which constitutes an electric double layer capacitor. Because the distance between the two charge layers is very small (generally less than 0.5mm), coupled with the use of a special electrode structure, the surface area of the electrode is increased tens of thousands of times, resulting in a great electric capacity.

The area of the ultra capacitor is based on porous carbon material. The porous structure of the material allows its area to reach 2000m2/g, and a larger surface area can be achieved through some measures.

The distance the ultra capacitor charges are separated is determined by the size of the electrolyte ions that are attracted to the charged electrodes. This distance is smaller than that achieved by traditional capacitor film materials. This huge surface area coupled with a very small charge separation distance makes supercapacitors have a surprisingly large electrostatic capacity compared to traditional capacitors, which is also where its "super" or "ultra" is.

https://www.kamcappower.com/is-supercapacitor-an-emerging-choice-for-automotive-emergency-starting-power-supply.html

As a portable power bank, the car emergency starting supercapacitor power supply can start the car when the ultracapacitor car battery loses power or cannot start the car for other reasons, and it has become one of the must-have products for people to travel outdoors. This type of power supply has higher requirements for discharge rate due to the need to ignite the car. At present, there are two types of batteries and super capacitors available in the market.

1. The difference between batteries and super capacitors in use

The automobile emergency starting power supply has higher requirements for the discharge rate. At present, there are two types of batteries and super capacitors available in the market. In the course of use, the shortcomings of battery products are gradually exposed: harsh requirements for the operating environment of the product, long charging time, and short cycle life.

In contrast, the characteristics of super capacitors are more prominent: high efficiency, high current discharge, wide voltage, wide temperature range, long cycle life, maintenance-free, and more suitable for emergency startup.

Ⅱ. The advantages of using super capacitors

In recent years, the emergence of automotive emergency starting power super capacitors is relatively new. These products have high current discharge characteristics, and their high rate discharge characteristics are comparable to battery products. At the same time, they have absolute advantages such as wide operating temperature range, fast discharge and long service life.

As an emerging choice for automotive emergency starting power supplies, the characteristics of automotive supercapacitors, such as high power density and fast charging and discharging, fully meet the rapid response requirements of vehicle startup, and will play an increasingly important role in this field.

How to Use Super Capacitor Correctly(2024年04月21日)

kamcappower — 2024-04-17T18:07:39+0900

https://www.kamcappower.com/how-to-use-super-capacitor-correctly.html

How to Use Super Capacitor Correctly
When using ultra capacitor, if the voltage exceeds the rated voltage of the unit, the service life of the unit will be reduced. For high-reliability super capacitor, how to maintain the voltage within the required range is the main point. Charging voltage must be controlled to make sure that it can not exceed the rated voltage of each unit. Before you buy supercapacitor, here are some information that you need to know.

1. Super capacitor has a fixed polarity. Polarity should be confirmed before use.
2. Supercapacitor should be used under nominal voltage: when the capacitor voltage exceeds the nominal voltage, it will lead to electrolyte decomposition. At the same time, the capacitor will be heated, the capacity will be reduced, and the internal resistance will increase, the life will be reduced. In some cases, it will lead to the collapse of capacitor performance.
3. Succos can not be used in high-frequency supercapacitor charging and discharging circuits. Fast charging and discharging at high frequencies will cause internal heating, capacity attenuation, internal resistance increase, and in some cases, the performance of capacitors will fall.
4. Supercapacitor lifetime: although different types of supercapacitor can have different lifetime. What we need to know is that external ambient temperature has an important impact on super caps lifetime. Capacitors should be as far away from heating sources as possible.
5. Voltage drop when supercapacitor is used as a backup power supply: Because ultra capacitor has considerable internal resistance, there is a voltage drop at the moment of discharge, V=IR.
6. Environmental gases in use: ultracapacitor should not be in places with a relative humidity greater than 85% of toxic gases, which will lead to corrosion of lead and capacitor shell and lead to circuit breakage.
7. Ultra capacitor storage: ultracapacitor can not be placed in high temperature and humidity environment, should be stored at - 30 + 50 C, relative humidity less than 60%, to avoid sudden temperature rise and drop, because this will lead to product damage.
8. Super capacitor in the use of double-sided circuit boards: When ultracap is used on double-sided circuit boards, attention should be paid to the place where the connection can not be touched by capacitors because the installation of Super capacitor/ultracap capacitor will lead to short circuit phenomenon.
9. When the capacitor is welded on the circuit board, the shell of the capacitor should not be contacted on the circuit board. Otherwise, welding material will penetrate the perforation of the capacitor, which will affect the performance of the capacitor.
10. After installing super caps, the capacitor should not be forced to tilt or twist, which will lead to a loosening of the capacitor lead and deterioration of its performance.
11. Avoid overheating capacitors during welding: If overheating occurs during welding, the service life of capacitors will be decreased. For example, if printed circuit boards with a thickness of 1.6mm are used, the welding process should be 260 C and the welding time should not exceed 5S.
12. Cleaning after welding: After welding capacitors, circuit boards and capacitors need to be cleaned, because some impurities may lead to a short circuit of capacitors.

Above are some tips about using supercapacitors. As a super capacitor factory, KAIMEI provides you with professional super capacitors and services. If you want to find out ultracapacitor price information, please make inquires through our website.

How to Make a Supercapacitor(2024年04月20日)

How to Make a Supercapacitor
Oct 21 , 2020
Supercapacitors are mainly composed of electrodes, electrolytes, diaphragms, current collectors, and other parts. The main function of the electrodes is to store energy. The main function of the diaphragm is to prevent short circuits inside the capacitor. The current collector is used to collect current and carry the active material of the electrode. For supercapacitors, the adhesion thickness of the electrode active material on the surface of the current collector and related processes will greatly affect the performance of the supercapacitor, which is the key to the manufacture of the supercapacitor. So how to make a supercapacitor?

Most commercial supercapacitors are cylindrical. This type of supercapacitor is mainly formed by winding two electrodes attached to the active material of the aluminum current collector. The separator is located between the two electrodes to prevent the formation of electronic short circuits. The ends are respectively located at the upper and lower ends of the winding core winding.

When the winding is completed, the prepared core winding is placed in a hard shell, and the positive and negative output ends are connected with the shell, and the electrolyte is injected for sealing to prevent impurities from polluting the electrolyte and active materials.

In order to improve the heat dissipation performance of the product, there is another supercapacitor on the market, which is a soft package supercapacitor. The production process of the product is similar to the production process of the soft-packaged lithium-ion battery. It is made by a lamination process. The electrodes with the same polarity are stacked and connected in parallel, and the product is sealed through an aluminum-plastic film. The price of this type of product is higher than that of cylindrical products because it has excellent heat dissipation performance and is suitable for ultra-high power application scenarios.

At present, cost reduction is a hot direction in the development of supercapacitors, mainly through the development of low-cost materials and research on new low-cost production processes to reduce production costs. Some studies believe that when the cost of materials drops by 90%, the price of supercapacitor products will drop by 50%. Some new production processes are currently in the research stage. It is expected that in the next few years, there will be a major breakthrough in the production process of supercapacitors. At that time, product prices will fall further.

How Super Capacitor/Ultra Capacitor Compensates For Leakage Current Changes(2024年04月19日)

kamcappower — 2024-04-17T18:05:02+0900

https://www.kamcappower.com/how-supercapacitor-ultra-capacitor-compensates-for-leakage-current-changes.html

Any Super capacitor/ultra capacitor will discharge through an internal shunt resistance in the case of electrification. This supercapacitor discharge current is called leakage current, which affects the self-discharge of the low leakage supercapacitor/ultra capacitor unit. Similar to some secondary battery technologies, the voltage of Super capacitor/ultra capacitor also needs to be balanced when used in series, because the leakage current exists in the super capacitor, and the magnitude of the internal shunt resistance determines the voltage distribution on the series Super capacitor/ultra capacitor unit. When the voltage of ultracapacitor is stable, the voltage on each cell will change with the supercapacitor leakage current, not with the capacitance. The larger the leakage current, the smaller the rated voltage. On the contrary, the smaller the leakage current, the higher the rated voltage. This is because the leakage current will cause the discharge of Super capacitor/ultra capacitor cells and reduce the voltage, which will then affect the voltage of other cells connected in series. It is assumed that these cells in series are powered by the same constant voltage.

In order to compensate for leakage current supercapacitor changes, a common method is to connect a resistor in parallel beside each unit to control the leakage current of the whole unit. This method effectively reduces the change of the corresponding shunt resistance among the units.

Another recommended method is the active cell balance method, in which each cell is actively monitored and balanced when there is a voltage change. This method can reduce any additional load on the unit and greatly improve the work efficiency.

High-end Sports Cars Fall In Love with Super Capacitors, or Will Drive the Entire Passenger Car Market(2024年04月18日)

kamcappower — 2024-04-17T18:03:56+0900

https://www.kamcappower.com/high-end-sports-cars-fall-in-love-with-super-capac.html

Guide: Rolls-Royce, Lamborghini and other sports car companies announced that they will develop research and development around high-energy storage technologies such as supercapacitors for new models. Thanks to the current development of electrochemical basic materials science, supercapacitors will also have a certain high energy density while maintaining the original high power density characteristics, thus providing strong power and acceleration for the car.

In the last two years, top sports car manufacturing companies have frequently released research and development news on new concept models based on supercapacitor energy storage. Rolls-Royce has signed a cooperation agreement with British technology companies to explore the potential of using new hydrophilic polymers to develop a new generation of high-energy storage technologies. The latter patented the new polymer super-dielectrics discovered in the study and is working to commercialize it for supercapacitor electrolyte materials and electrical energy storage. Lamborghini announced that it would work with MIT to develop a new supercar that would be powered by supercapacitors, which is different from conventional batteries.

Analysts pointed out that the top sports car company has never been concerned about the research and development of energy storage devices such as super capacitors, and the heat even surpasses the trend of traditional batteries. Although the Tesla CEO's assertion that lithium battery will be too high, super capacitor is king - too radical, but it also reflects the super capacitor in the global passenger car application is optimistic.

Prior to this, the main commercial application of supercapacitors in passenger cars was hybrid braking energy recovery, such as Mazda Artz's use of the i-Eloop braking energy recovery system based on supercapacitor energy storage to slow down the vehicle. The generated kinetic energy is converted into electricity for use in air conditioners, stereos, and other in-vehicle electrical equipment, reducing fuel consumption during actual driving with frequent acceleration and braking. The technology is derived from the Toyota Le Mans LMP1 car, which uses "supercapacitor" to quickly charge and recharge the power, long-term repeated use and not easy to age energy storage characteristics. In the modification super capacitors market, supercapacitors are often used in car audio, and certain compensation is performed when the starting or vehicle voltage fluctuates, so that the speaker is not affected.

In recent years, supercapacitors have been frequently concerned by super sports car companies; they are related to the high power discharge characteristics inherent in supercapacitors, and are also related to the development of new electrochemical materials. The synergy between the two makes high energy density and high power density. The commercialization of supercapacitors has certain theoretical possibilities.

(1) High power density. The internal resistance of the supercapacitor is very small, and the charge storage can be quickly stored and released in the electrode/solution interface and the electrode material body, so that its output power is up to several KW/kg, which is unmatched by any chemical power source. Tens of times the battery is generally used.

(2) Breakthrough in capacitive material technology. The successful development and application of new graphene materials, carbon nanostructured composite electrode materials, and various high-performance materials such as new water/organic electrolytes can not only maintain the fast charge and discharge advantages of supercapacitors, but also increase the storage capacity.

During the period, the supercapacitor company's own transformation and innovation is also indispensable: foreign supercapacitor suppliers, develop supercapacitor batteries for automotive use, and superpower leader Jixing Technology also has initial intentional communication with a domestic brand passenger car. The research model provides energy storage support. In this way, will high energy capacitors be far behind?

We supply high-quality ultracapacitors, including coin type supercapacitor, winding type supercapacitor, combined type supercap capacitor, module supercaps, high temperature supercap and hybrid capacitor.

Difference between Capacitor and Supercapacitor(2024年04月17日)

kamcappower — 2024-04-17T18:03:14+0900

https://www.kamcappower.com/difference-between-capacitor-and-supercapacitor.html

Supercapacitor, also known as Electrical Doule-Layer Capacitor (EDLC), Gold Capacitor, Farad capacitor. The biggest difference between capacitor and supercapacitor is that supercapacitor is an electrochemical physical component, but does not react chemically itself, the capacitor supercapacitor has a particularly large storage capacity, reaching farad-level capacity. How do you increase the area of the two poles? Supercapacitors store energy by injecting electrolytes. Under the action of the electrode, the charge on the electrode surface will attract the heterogeneous ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, constituting a double layer capacitance.

Because the distance between the two charge layers is very small (generally less than 0.5mm), and use of special electrode structure is adopted, the surface area of the electrodes is increased by ten thousandfold, resulting in a tremendous amount of electrical capacity.

Supercapacitors combine the physical characteristics of ordinary capacitors with many advantages that conventional capacitors and batteries cannot match:

1. Supercapacitors have a large Faraday-level electrical capacity, which is much larger than ordinary capacitors.

2. Supercapacitors can instantly release power nearly ten times higher than ordinary batteries, and will not be damaged.

3. The cycle life of charge and discharge is more than 100,000 times, which is one of the biggest advantages. Conventional batteries can only be recharged a few hundred times.

4. Supercapacitors can be used normally in an ambient temperature of 40 degrees to 60 degrees, the performance of traditional batteries will be greatly reduced in low temperature.

5. Super charge holding capacity, leakage is very small, traditional batteries need to be charged frequently to maintain the state.

6. Biggest supercapacitors can charge rapidly, its speed is dozens of times faster than ordinary batteries, a few minutes can be full of electricity required for a car.

7. Supercapacitors will not inherently pollute the environment, truly maintenance-free, while traditional batteries are still polluting.

In some fields, supercapacitors already have a promising future, for example, mobile phone batteries made of supercapacitors can be fully charged in just one minute, and are not afraid of subzero temperatures. There are different types of supercapacitor.

The Development Trend of Ultracapacitor Ups(2023年10月07日)

kamcappower — 2023-09-22T15:04:54+0900

https://www.kamcappower.com/the-development-trend-of-ultracapacitor-ups.html

Currently, supercapacitors are limited by their low energy density and are mainly used as an auxiliary power source, but are rarely used as the main power source. Great breakthroughs in the application field of the ultracapacitor ups market depend on continuous breakthroughs in ultracapacitor ups technology in the future, and the development trends of ultracapacitor ups are as follows:

1) Low cost and high energy density. As the main power source of equipment or systems in the future, ultra capacitors will require high energy density and low cost;

2) Ultra-high power density, low maintenance cost, and long life. The development of supercapacitors to higher power density, maintenance-free, and long life will be able to compensate for the shortcomings of the low energy density of products to a certain extent, and can further expand the market share in some special fields. The organic system supercapacitors are expected to be the first to realize ultra-high power breakthrough;

3) The research on the aging mechanism of supercapacitors in different application fields and the research on the control strategy of the ultra capacitor energy storage system will be another research hotspot of supercapacitors, which will help to optimize the design of supercapacitor energy storage system and minimize the cost of system design.

If there are major breakthroughs in the above-mentioned technologies, supercapacitors will have greater advantages in terms of power density, maintenance costs, service life, and environmental adaptability compared with battery energy storage, and it will become an ideal choice for energy storage systems in the electrical, power, and electronics industries.

The Development Trend of Automotive Super Capacitor Technology in the Next Few Years(2023年10月06日)

kamcappower — 2023-09-22T15:04:20+0900

https://www.kamcappower.com/the-development-trend-of-automotive-super-capacito.html

The development goal of automotive super capacitors is to continuously pursue higher energy and higher power products on the premise of maintaining long life, high safety and high reliability. Based on this goal, the current technology development trends mainly include the following aspects:

1. High performance and low cost carbon materials for super capacitors

Carbon materials are the core key raw materials for super capacitors. Whether it is an electric double layer capacitor, a lithium ion capacitor or an energy hybrid super capacitor, the activated carbon material with higher capacity, long life and low cost is an indispensable part. At present, there are two main raw materials for common activated carbon materials: coconut shell charcoal with conventional capacity and low cost and coke with high capacity and high cost. The development of high-capacity and low-cost activated carbon materials is a goal that the super capacitor industry has been pursuing.

2. Advanced electrode manufacturing technology for super capacitors

The core technology of super capacitors is the electrode manufacturing process. The high-performance electrode manufacturing process can bring about a great improvement in product performance.

3. Electrolyte technology with wide temperature and high voltage for super capacitors

super capacitor electrolyte with a working temperature of 85°C is in urgent need in the automotive field; improving the voltage withstand capability of super capacitors is the most direct way to increase the energy density of the product. Small-capacity super capacitors have been increased from the traditional 2.7V working voltage to 3V supercapacitor, but the large-capacity 3.0V super capacitors still have many problems; the development of high-performance electrolyte is imminent.

4. Better electrode compounding technology for super capacitors and optimization of positive and negative electrode ratios

For lithium ion capacitors and energy hybrid super capacitors, the combination of electrodes and the optimization of the ratio of positive and negative electrodes means the improvement of energy density and the guarantee of long life. Research on electrode compound technology and optimization of positive and negative electrode ratios, and continuously improve the energy density of lithium ion capacitors and energy hybrid super capacitors, is the goal pursued by the car supercapacitor industry.

The Combination of Super Capacitor and Battery Improves Car Starting Performance(2023年10月05日)

kamcappower — 2023-09-22T15:03:38+0900

https://www.kamcappower.com/the-combination-of-super-capacitor-and-battery-imp.html

1. Improve electrical performance of super capacitors

Compared with the start when the super caps battery is connected in parallel with the battery, the instantaneous voltage drop at start is increased from 3.2V to 7.2V when only the battery is used; the starting current is increased from 560A to 1200A; the instantaneous power output power is increased from 2kW to 8.7kW; the steady voltage during the starting process is increased from 7V to 9.4V; the steady current during the starting process is increased from 280A to 440A; the steady output power of the power supply during the starting process is increased from 2.44kW to 4.12kW.

2. Improve starting performance of super capacitors

The parallel application of supercapacitor battery car can improve the starting performance of locomotives. Parallel super capacitors (450F/16.2V) with 12V, 45Ah batteries to start a car with a 1.9-liter diesel engine will start smoothly at 10℃, although in this case, when the super capacitor is not connected, the battery can also be started, but the speed and performance of starting the motor when the super capacitor is connected in parallel with the battery are very good.

Due to the increase in the output power of the power supply, the starting speed has been increased from 300 rpm when the battery is only used to 450 rpm; especially in improving the starting performance of the car in cold weather (higher starting torque), the super capacitor is very meaningful, at -20℃, because the performance of the battery is greatly reduced, it is likely that it cannot start normally or requires multiple starts to succeed, and when the super capacitor is connected in parallel with the battery, only one ignition is required.

3. Improve application state of the battery by the super capacitor

When the commercial super capacitor is connected in parallel with the battery, the equivalent series resistance (ESR) of the super capacitor is much lower than the internal resistance of the battery. Therefore, the 800A of the 1200A starting current at the moment of starting is provided by the super capacitor, and the battery only provides 400A.

It is significantly lower than the 560A that only uses the battery, which effectively reduces the polarization of the battery plate, prevents the increase in the internal resistance of the battery, and improves the stable voltage during the start-up process. The most important thing is the reduction in the polarization of the battery plates, which not only helps to extend the service life of the battery, but also eliminates the impact of frequent starting on the battery life.

Supercapacitors for Wind Energy(2023年10月03日)

https://www.kamcappower.com/super-capacitor-ultracapacitor-wind-energy.html

Capacitor for Wind Power
As the fastest growing renewable energy power generation technology, wind power has broad application prospects. However, wind energy is a randomly varying energy source. Wind speed changes can cause fluctuations in the output power of wind turbines, which can affect the power quality of the grid.

At present, the active power fluctuation of wind power mostly adopts the method of directly adjusting the operating state of the wind turbine to smooth its output power, but the power adjustment capability of the method is limited; the reactive power fluctuation usually adopts the parallel static reactive power compensation device for reactive power adjustment, but no The power compensation device cannot stabilize the active power fluctuations. By adding energy storage equipment, it is possible to adjust the reactive power, stabilize the bus voltage of the wind farm, and adjust the active power in a wide range. Wind power research shows that the fluctuating power at 0.01Hz-1Hz has the greatest impact on the power quality of the grid. The wind power fluctuation in this frequency band has the greatest impact on the power quality of the grid. Suppressing the wind power fluctuation in this frequency band can be achieved by using short-term energy storage. Therefore, the small-capacity energy storage device capable of realizing short-term energy storage has high application value to wind power generation. Due to its tens of thousands of cycles of charge and discharge cycle life and high current charge and discharge characteristics, supercapacitors can adapt to high current fluctuations of wind energy. It can absorb energy under conditions of sunny or strong wind during the day, and weak at night or wind. When it is discharged, it can smooth the fluctuation of wind power and achieve more efficient grid connection.

Why Can a Dual-Powered Super Capacitor/Ultra Capacitor Electric Car Save Fuel? Why Can Pollution Be Reduced?(2023年10月02日)

kamcappower — 2023-09-22T15:02:06+0900

https://www.kamcappower.com/super-capacitor-ultra-capacitor-electric-car-can-save-fuel.html

The biggest advantage of dual power supercapacitor electric car is to give full play to super capacitor in the case of low speed and heavy load, the energy is not lost; in the case of deceleration, downhill, and braking, the energy can be recovered. Avoiding the internal combustion engine running at low speed and heavy load, and running at high speed and high load and oil consumption, the engine will always run in the optimum condition, which saves oil and reduces pollution. The dual power super capacitor electric car can save 30%~50% of the fuel and 70%~90% of pollution.
—— Start-up stage: low speed, heavy load, and oil consumption; in this stage, the internal combustion generator unit operates in the optimum state, at which time it needs to start and accelerate with supercaps and charge to ultra capacitor.
—— Normal Operation Stage: At this time, the internal combustion generator unit is operating in the optimum state and outputs power to the motor. At this time, the busload is the smallest, and the most fuel-efficient, and charges to ultra capacitor.
—— High-speed operation stage: Internal combustion generators output stable power to the motor, and ultracapacitor also output power to the motor. In this stage, the motor speed is high, the load is large, and the bus speed is the fastest.
—— Braking, parking, deceleration, downhill stage: at this time, the generator unit, supercapacitor stop exporting power to the motor. At this time, the kinetic energy reserved by the bus is transformed into the generator charging to ultra capacitor, which can absorb 70% of the kinetic energy, especially in urban public transport, and can save energy or fuel.

Super Capacitors Will Be an Important Part of the Automotive and New Energy Industries(2023年06月01日)

kamcappower — 2023-06-01T12:27:22+0900

https://www.kamcappower.com/super-capacitors-will-be-an-important-part-of-the-automotive-and-new-energy-industries.html

The development of super capacitors has gone through more than 30 years. At present, miniature supercapacitors are widely used in small electromechanical devices (such as computer memory systems, cameras, audio equipment), while large-size cylindrical supercapacitors are mostly used in the automotive field and new energy fields.

In terms of future development, super capacitors will be an important part of the automotive and new energy industries.

1. The international market situation of super capacitors
At present, the super capacitor industry has become one of the hot topics of research in many countries and regions.

Japan, the United States, and Europe have all regarded the supercapacitor project as a national-level key research and development project, and proposed short-term and mid- to long-term development plans. The USMSC plan in the United States, the New Sunshine plan in Japan and the PNGU plan in Europe all include supercapacitors in the development content.

China has included the "Research and Preparation Technology of Key Materials for Supercapacitors" in the "National Medium and Long-term Science and Technology Development Program (2006-2020)" as one of the frontier technologies in the energy field. During the "Twelfth Five-Year Plan" period, driven by low-carbon, energy-saving, and environmental protection policies, China's large-capacity (above 100F, even up to 200,000 F) and higher power (such as 8~10kW/kg) supercapacitor market is stepping up on a track of rapid development.

2. Technical breakthroughs in the development of super capacitors
As a typical capital-intensive industry, the key technology of super capacitors still requires constant innovation and breakthroughs by industry insiders.

First of all, how to obtain high-performance, low-cost carbon materials will become the key to technological breakthroughs. Throughout the electric double layer capacitors, there are "six highs" in the performance of porous capacitive carbon materials, that is, high specific surface, high porosity, high conductivity, high bulk density, high purity, and high cost performance. These indicators contradict each other and are extremely difficult to balance. They must be carefully adjusted and optimized. In the cost of supercapacitors, ultra-high specific surface activated carbon, which is a fine chemical product, accounts for a large part.

Secondly, as the core technology of supercapacitors, technological breakthroughs in high-conductivity electrolytes are equally important. While continuously improving key technologies such as performance, Chinese supercapacitor manufacturers are also actively expanding their production scale to achieve better scale efficiency and reduce usage costs, while at the same time having a deep understanding of the application needs of different industries and developing targeted technical solutions.

In the next few years, it is believed that driven by the huge market demand of new energy vehicles, solar energy, wind power, rail transit, etc., breakthroughs in the core technology of supercapacitors and cost reductions will be gradually realized, and the "spring" of supercapacitors will also be getting closer.

Super capacitors make it easier for diesel vehicles to start at low temperatures(2023年06月01日)

kamcappower — 2023-06-01T12:26:41+0900

https://www.kamcappower.com/super-capacitors-make-it-easier-for-diesel-vehicles-to-start-at-low-temperatures.html

When the temperature reaches below minus 10 degrees, the high-current output performance of the vehicle battery is greatly reduced, resulting in the inability to drive the diesel engine to start. As a high-performance energy storage device, supercapacitors can effectively maintain high-current output performance at low temperatures, and the low-temperature startup advantage is very obvious.

Vehicles driven by kam diesel engines, without exception, are powered by a dedicated lead-acid battery to drive the starter motor, thereby driving the diesel engine to compression ignition. During the starting process, the input current power required at the moment of starting the motor is very large. The best working temperature of the commonly used lead-acid batteries is 10°C～40°C. Under low-temperature conditions, the viscosity of the electrolyte increases. The penetration capacity of the plate decreases and the internal resistance increases, which leads to a significant decrease in the terminal voltage and capacity of the battery and a decrease in output power when starting, and the inability to support the starter to drive the diesel engine to reach the minimum starting speed makes it difficult to start the vehicle.

In contrast, the characteristics of supercapacitors such as high power density, high current charge, and discharge capabilities, and long cycle life fully meet the needs of vehicle startup. The good power characteristics at low temperatures make it incomparable in the low-temperature startup of diesel engines.

KAMCAP Supercapacitor a leader in supercapacitors, provides supercapacitor energy storage units for various types of vehicles to start power sources, ensuring that vehicles start normally under low power, no power, and low-temperature conditions. Supercapacitors use the double electric layer formed by activated carbon and electrolyte to obtain super large capacitance. At the same time, they adopt a structure that is conducive to excessive current, which has high power density and strong instantaneous discharge capability. The characteristics of the new organic electrolyte support normal operation under minus 40 ℃ environmental conditions, and the cold start efficiency is high.

In low-temperature environments, the parallel application of supercapacitors and batteries can provide a higher starting current for the car, so that its starting performance can be exerted to a greater extent, which undoubtedly brings "starting" gospel to high-latitude, ultra-low temperature vehicles. The era of "fear of the cold" when the car starts may be over.

Ultracapacitor Manufacturers Explain the Development History of Supercapacitors for You

Supercapacitors are electrochemical components developed from the 1970s and 1980s that use polarized electrolytes to store energy. It is different from the traditional chemical power supply. It is a power supply with special performance between traditional capacitors and batteries. It mainly relies on an electric double layer and redox pseudocapacitor charge to store electric energy.

In 1879, Helmholz discovered the properties of double-layer capacitors and proposed the concept of electric double layers, but the use of electric double layers for energy storage is only a matter of recent decades. In 1957, Bcker first proposed that a smaller capacitor can be used as an energy storage device, which has specific energy close to that of a battery. In 1968, Standard Oil Corporation Sohio first proposed a patent for making double-layer capacitors using high-specific surface area carbon materials and transferred the patented technology to NEC. NEC began to produce supercapacitors for the start-up system of electric vehicles in 1979.

As a product, supercapacitors have become mature, and their application scope has been continuously expanded. They have been widely used in industries, consumer electronics, communications, medical equipment, national defense, military equipment, and transportation. From small-capacity special energy storage to large-scale electric energy storage, from separate energy storage to hybrid energy storage combined with batteries or fuel cells, supercapacitors have demonstrated unique advantages. The United States, Europe, Japan, South Korea, and other developed countries and regions have conducted fruitful research on the application of supercapacitors.

Supercapacitor Energy Storage Mechanism(2023年06月01日)

kamcappower — 2023-06-01T12:25:23+0900

https://www.kamcappower.com/supercapacitor-energy-storage-mechanism.html

Supercapacitor energy storage means using an electric double-layer structure composed of activated carbon porous electrodes and electrolyte to obtain a large capacitance. Unlike batteries that use chemical reactions, the charging and discharging process of supercapacitors is always a physical process. Short charging time, long service life, good temperature characteristics, energy-saving, and environmental protection. There is nothing too complicated about supercapacitors, that is, capacitor charging, and the rest is a matter of materials. The current research direction is whether it can achieve a small area and a larger capacitance. The development of supercapacitors is very fast. At present, new types of supercapacitors based on graphene materials are very popular.

The supercapacitor is a new type of electrochemical energy storage device between traditional capacitors and batteries. Compared with traditional capacitors, it has a higher energy density, and its electrostatic capacity can reach a thousand farads to ten thousand farads. Compared with batteries, it has higher energy density and long cycle life, so it combines the advantages of traditional capacitors and batteries, which is a chemical power supply with broad application prospects.

Kamcap super capacitor energy storage mainly uses the electric double layer formed by the charge separation of the electrode/electrolyte interface, or the Faraday "quasi-capacitance" generated by the rapid redox reaction on the electrode surface and inside to realize the storage of charge and energy. Therefore, supercapacitors have the characteristics of fast charging speed, good high-current discharge performance, ultra-long cycle life, and wide operating temperature range. The supercapacitor energy storage device is mainly composed of a supercap capacitor bank, a bidirectional DC/DC converter, and corresponding control circuits.

Supercapacitor Applications in Solar Energy Field(2023年06月01日)

kamcappower — 2023-06-01T12:24:54+0900

https://www.kamcappower.com/supercapacitor-applications-in-solar-energy-field.html

Solar energy is ideal clean energy for energy conservation and environmental protection, and the energy storage characteristics of the physical process of supercapacitors determine that the solar supercapacitor charger applications have inherent advantages, which can absorb natural and unstable solar energy to achieve stable voltage output.

Due to the unstable input voltage of solar energy, energy storage devices must be equipped, but the current battery life is short and it has pollution, so supercapacitors are selected as energy storage devices. The power performance of the charging supercapacitors with solar is much better than that of the battery, the charging speed is fast, there is no over-discharge problem, and the life is long. The charge and discharge can reach hundreds of thousands of times. The energy storage characteristics of the super capacitor's physical process determine its use in solar energy. It has natural advantages in application, absorbing all the electric energy generated by solar panels, and achieving the purpose of energy-saving and environmental protection.

When the output voltage of the solar cell is lower than the voltage of the super capacitor, the supercapacitor will not charge the solar cell in the reverse direction, so as to avoid unnecessary energy loss.

Supercapacitors overcome the shortcomings of short service life, slow charging and discharging speed, inability to quickly respond to changes in photovoltaic output voltage and a certain delay in general batteries. In the case of sufficient light during the day, the solar battery charges the load. When the light is insufficient or at night, the supercapacitor can be used to supply power to the load. The supercapacitor can be used as a green energy storage element. It is believed that as the capacity of supercapacitors increases, there will be more and more comprehensive utilization of solar cells and supercapacitors.

The Combination of Super Capacitor and Battery Improves Car Starting Performance(2022年10月27日)

kamcappower — 2022-10-27T12:40:22+0900

https://www.kamcappower.com/the-combination-of-super-capacitor-and-battery-imp.html

1. Improve electrical performance of super caps battery

Compared with the start when the super capacitor is connected in parallel with the battery, the instantaneous voltage drop at start is increased from 3.2V to 7.2V when only the battery is used; the starting current is increased from 560A to 1200A; the instantaneous power output power is increased from 2kW to 8.7kW; the steady voltage during the starting process is increased from 7V to 9.4V; the steady current during the starting process is increased from 280A to 440A; the steady output power of the power supply during the starting process is increased from 2.44kW to 4.12kW.

2. Improve starting performance of super capacitors

The parallel application of super capacitors and batteries can improve the starting performance of locomotives. Parallel super capacitors (450F/16.2V) with 12V, 45Ah batteries to start a car with a 1.9-liter diesel engine will start smoothly at 10℃, although in this case, when the super capacitor is not connected, the battery can also be started, but the speed and performance of starting the motor when the super capacitor is connected in parallel with the battery are very good.

3. Improve application state of the battery by the super capacitor

When the commercial supercapacitor is connected in parallel with the battery, the equivalent series resistance (ESR) of the super capacitor is much lower than the internal resistance of the battery. Therefore, the 800A of the 1200A starting current at the moment of starting is provided by the super capacitor car battery, and the battery only provides 400A.

Why Can a Dual-Powered Super Capacitor/Ultra Capacitor Electric Car Save Fuel? Why Can Pollution Be Reduced?(2022年10月27日)

kamcappower — 2022-10-27T12:38:57+0900

https://www.kamcappower.com/super-capacitor-ultra-capacitor-electric-car-can-save-fuel.html

The biggest advantage of dual power ultracapacitor for electric vehicle is to give full play to super capacitor in the case of low speed and heavy load, the energy is not lost; in the case of deceleration, downhill, and braking, the energy can be recovered. Avoiding the internal combustion engine running at low speed and heavy load, and running at high speed and high load and oil consumption, the engine will always run in the optimum condition, which saves oil and reduces pollution. The dual power supercapacitor electric car can save 30%~50% of the fuel and 70%~90% of pollution.
—— Start-up stage: low speed, heavy load, and oil consumption; in this stage, the internal combustion generator unit operates in the optimum state, at which time it needs to start and accelerate with supercaps and charge to ultra capacitor.
—— Normal Operation Stage: At this time, the internal combustion generator unit is operating in the optimum state and outputs power to the motor. At this time, the busload is the smallest, and the most fuel-efficient, and charges to ultra capacitor.
—— High-speed operation stage: Internal combustion generators output stable power to the motor, and ultracapacitor also output power to the motor. In this stage, the motor speed is high, the load is large, and the bus speed is the fastest.
—— Braking, parking, deceleration, downhill stage: at this time, the generator unit, supercapacitor stop exporting power to the motor. At this time, the kinetic energy reserved by the bus is transformed into the generator charging to ultra capacitor, which can absorb 70% of the kinetic energy, especially in urban public transport, and can save energy or fuel.

Solar energy is ideal clean energy for energy conservation and environmental protection, and the energy storage characteristics of the physical process of supercapacitors determine that the solar supercapacitor applications have inherent advantages, which can absorb natural and unstable solar energy to achieve stable voltage output.

Due to the unstable input voltage of solar energy, energy storage devices must be equipped, but the current battery life is short and it has pollution, so supercapacitors are selected as energy storage devices. The power performance of the supercapacitor is much better than that of the battery, the charging speed is fast, there is no over-discharge problem, and the life is long. The charge and discharge can reach hundreds of thousands of times. The energy storage characteristics of the super capacitor's physical process determine its use in solar energy. It has natural advantages in application, absorbing all the electric energy generated by solar panels, and achieving the purpose of energy-saving and environmental protection.

When the output voltage of the solar cell is lower than the voltage of the supercapacitor, the best super capacitor will not charge the solar cell in the reverse direction, so as to avoid unnecessary energy loss.

Advantages Of Super Capacitor/Ultra Capacitor(2021年)

kamcappower — 2021-11-24T15:05:34+0900

https://www.kamcappower.com/products/

Conventional capacitors can only meet the requirements of circuit operation with a simple structure and small load, but it is difficult to store charge for circuit operation with a large load. In recent years, the popularization and application of supercaps have effectively solved the problem of large load circuit operation and ensured the normal performance of power electronic equipment.
Super capacitor advantages
Ultra capacitors are the upgrade of ordinary capacitor devices, and many improvements have been made to the early capacitors. The main advantages are (1) capacitance. The conventional capacitors used in the early stage have small capacitor storage capacity, which can only meet the needs of small load circuit; while the capacitor level of super capacitor can reach farad level, which can meet the needs of more complex circuit operation. (2) Circuit. Ultra capacitor has a low requirement on the circuit structure. It does not need to set up a special charging circuit and control discharge circuit, and the service time of capacitor will not be affected by overcharge and over-discharge. Welding. Common capacitors can not be welded. When Supercapacitor is installed, welding treatment can be carried out according to the need, which prevents the occurrence of bad battery contact and improves the performance of capacitor components.
However, super capacitor is not superior in every aspect of the use process, which requires that the advantages and disadvantages of the device be mastered skillfully when using supercaps. Due to the limitation of manufacturing technology, there are still some shortcomings in installation and debugging when using super capacitor in China. Many devices cause circuit failure because of blindly using ultra caps, which affects the performance of the whole equipment. However, as a new product of capacitors, ultracapacitor has more advantages than disadvantages.

What Is Super Capacitor/Ultra Capacitor(2021年)

kamcappower — 2021-11-24T15:04:58+0900

https://www.kamcappower.com/products/high-temperature-super-capacitors/

In applications requiring high reliability but not high energy requirement, Supercapacitor can be used to replace traditional batteries, or UltraCap can be combined with batteries, which can be used in situations requiring high energy, and smaller and more economical batteries can be used.
The ESR value of ultra capacitor is very low, so it can output more current and absorb large current quickly. Compared with chemical charging principle, Supercapacitor's working principle makes the product performance more stable, so the service life of ultracapacitor will be longer. Super capacitor/ultra capacitor is undoubtedly the most ideal power source for devices such as power tools and toys that need fast charging.
Some products are suitable for battery, Super capacitor/ultra capacitor hybrid systems. Super capacitor/ultra capacitor can avoid using large batteries to obtain more energy. For example, digital cameras in consumer electronics, the use of Super capacitor/ultra capacitor allows digital cameras to use cheaper alkaline batteries rather than expensive Li-ion batteries.
Super capacitor/ultra capacitor cell rated voltage ranges from 2.5 V to 2.7V, so it is necessary to use multiple Super capacitor/ultra capacitor cells in many applications. When connecting these units in series, the design engineer needs to consider the balance and charging between the units.

Notes For Using Super Capacitor/Ultra Capacitor(2021年)

kamcappower — 2021-11-24T15:04:26+0900

https://www.kamcappower.com/products/

Super capacitor can maintain long service life without failure as long as it works within the specified operating parameters. Super capacitor will last longer than most other electronic components in any given application, which is why ultra capacitor is the best transmission device in harsh environments.
However, if used improperly, Super capacitor will also be damaged in advance, although there are not many reasons for the premature damage of ultra capacitor (the following items). Please note the following to ensure that the ultra capacitor in the system achieves the longest service life.
Working temperature: Super capacitor does not generate or provide power or energy through electrochemical reactions. Simply , it is achieved by static electricity. Obviously, electrochemical reactions in super capacitor are not only non-existent but also unnecessary. Higher temperature will catalyze the chemical reaction and accelerate the reaction rate. This applies equally to super caps because ultra capacitor is also a chemical system. Therefore, if we want to break down the service life of supercapacitor and let it work beyond the rated operating temperature range, it will surely rapidly attenuate its capacitance, increase its resistance at an unimaginable rate, and seriously reduce its efficiency. The magnitude of the damaging effect is proportional to the range and duration of overheating.
Working voltage: The electrochemical system generally has a stable working voltage range, beyond which the system will become unstable from the electrochemical point of view. As with overheating, the consequences of overvoltage include accelerated capacitance decline and accelerated resistance rise. Overpressure also increases the gas production rate of the monomer. If the overpressure is serious, the gas will increase to a certain extent, which will cause the internal pressure of the single body to be too large and rupture, and then immediately fail. Ultra cap, unlike some other electrochemical energy storage technologies, has no Undervoltage limitation. In fact, although the reverse voltage should not be applied, as long as the reverse voltage does not exceed the absolute value of the normal rated voltage, it will not destroy the supercaps or cause danger. Like temperature, the effect of overpressure depends on the magnitude and duration of overpressure.
Mechanical abuse: Let ultracapacitor work beyond the mechanical parameters (such as vibration or impact standards), except for the most robust structure, can not be immune. Sometimes it fails immediately.

The Supercapacitors: its Basic Principles, Classification, and its Electrical Performance(2021年)

kamcappower — 2021-11-24T15:03:54+0900

https://www.kamcappower.com/products/

In these days, the energy storage systems are playing an increasingly important role in different fields, and the relatively typical fields are like electric vehicles, power systems and some other fields. In this context, the super capacitors, as an energy storage technology, possesses excellent performances such as high power density, maintenance-free, and long life, and it have become the focus of attention in academia and industry.

The basic principles and the classification of the supercapacitors
This section mainly will introduce the electrochemical mechanism of supercapacitors. The energy storage in supercapacitors is mainly in the interface between electrodes and electrolytes. This energy storage method has a great relationship with the electrode materials used. When the two electrodes of a supercapacitor are made from different types of materials, in this case, a comprehensive analysis of the energy storage mechanism of the product will not fully understand the working principle of the super capacitor. Based on this point, this section will briefly introduce the working principle of the super capacitor first; then elaborate the energy storage mechanism of different electrode-electrolyte interfaces, classify supercapacitors according to different electrodes and electrolytes, and introduce some electrical performance characteristics of supercapacitors.

Figure 1: Schematic diagram of supercapacitor structure and working principle

Ⅱ. The energy storage mechanism
There are many materials used in the manufacture and production of supercapacitor electrodes and electrolytes. In order to deeply understand the energy storage mechanism of supercapacitors and optimize the performance of supercapacitors, it is usually necessary to use two experiments, the cyclic voltammetry curve, and the constant current discharge to characterize the electrode performance of the different supercapacitor. Figure 2 shows two experiments, the cyclic voltammetry curve, and the constant current discharge of the supercapacitor, under different energy storage mechanisms, where a and c represent the cyclic voltammetry curve and the constant current discharge curve of the supercapacitor electrode, under the storage mechanism of electric double layer capacitance and pseudo capacitance, respectively; b and d respectively represent the cyclic voltammetry curve and constant current discharge curve of the supercapacitor electrode under the Faraday capacitor storage mechanism.
Figure 2: Cyclic voltammetry curves and constant current discharge curves of electric double layer capacitors under different storage mechanisms

1. The storage mechanism of the electric double layer capacitor
The electric double layer effect is that the positive and negative charges should be separative, which are generated by the accumulation at the electrode-electrolyte interface. It is the main mechanism for energy storage of supercapacitors such as activated carbon, carbon fiber, carbon felt and other carbon materials. The formation of the electric double layer effect is mainly caused by the increase or decrease of high-energy conduction band electrons on the electrode surface, which causes the movement of positive and negative charges in the electrolyte solution on the interface side, which is used to balance the charge imbalance caused by the change of the high-energy conduction band electrons on the electrode surface.

Considering the charge density on the electrode surface is depended by the applied voltage, the electric double layer capacitance differs depending on the voltage. The electrochemical reaction in the electric double layer capacitor mainly occurs on the electrode surface, and it is usually the adsorption and desorption behavior of anions and cations. The cyclic voltammetry curve of the electric double layer capacitor has a rectangular shape as shown in Fig. 2 (a), and the constant current discharge curve of this type of material has a linear relationship, as shown in Fig. 2 (c).

The electric double layer effect occurs at the interface between the electronic conductor and the ionic conductor, which is present in almost all electrochemical energy storage systems. However, it is generally regarded as a side reaction in electrolyzers, fuel cells, and batteries, and it will not be regarded as the main energy storage mechanism. On the contrary, the working principle of supercapacitors is based on this effect, which requires supercapacitors to maximize this effect in the design and development process.

2. The pseudocapacitance storage mechanism
The pseudocapacitance, also known as Faraday pseudocapacitance, are the capacitance that related to the electrode charging potential, when it is two-dimensional or quasi-two-dimensional spaces in the electrode surface or bulk phase, and when the electroactive substances undergo underpotential deposition, and highly reversible chemical adsorption, desorption or oxidation, and reduction reactions occur. It is the main mechanism for energy storage of metal oxides, metal carbides, and conductive polymer supercapacitors. Although these reactions are very similar to those in batteries, because both their charges pass through the electric double layer capacitor, the difference is that the formation of pseudocapacitance is more like caused by special thermodynamic behavior. The cyclic voltammetry curve and constant current discharge curve of the pseudocapacitance are similar to the electric double layer capacitor. Unlike the electric double layer capacitor, the pseudo-capacitor has a higher energy density, but is limited by the electrochemical reaction kinetics and the irreversibility of the reaction. As a result, the charge and discharge power and cycle life of the pseudo capacitor are smaller than the electric double-layer capacitor. It should be pointed out that due to the presence of active functional groups, most supercapacitor electrodes have pseudocapacitance. For example, the electrochemical response of electric double layer capacitors composed of nanomaterials such as graphene is mainly formed by redox reaction caused by defects in carbon materials.

Some electrode materials that exhibit Faraday effect, such as Ni (OH) 2 or similar battery electrode materials, are considered to be pseudocapacitive materials in many literatures, which is confusing to the readers. Although this type of material has a higher energy storage energy density and is limited by the solid phase diffusion of the material ions, the high-power charge-discharge performance is far worse than the pseudocapacitance material.

Ⅲ. The classification of the supercapacitors
There are many classification standards for the supercapacitors. This article will mainly introduce two classification methods. The first one will be classified according to the different energy storage mechanisms of the electrode materials, and the second one will be classified according to the different electrolytes.

1. Classification according to different energy storage mechanisms
According to different energy storage mechanisms, supercapacitors can be divided into symmetric supercapacitors, asymmetric supercapacitors, and hybrid supercapacitors.

2. Classification according to different electrolytes
According to the electrolyte type, it can be conventionally divided into aqueous electrolytes and organic electrolytes. Among them, aqueous electrolytes include: 1. The acidic electrolytes, mostly using 36% H2SO4 aqueous solution as electrolytes. 2. the alkaline electrolytes, usually using strong bases such as KOH and NaOH as electrolyte, and water as solvent. 3. the neutral electrolyte, usually using KCl, NaCl and other salts as electrolyte, and water as solvent, mostly used for electrolyte of manganese oxide electrode material; the organic electrolyte usually uses lithium salt represented by LiClO4, TEABF4 as typical representative quaternary amine salts are used, the organic solvents usually use PC, ACN, GBL, THL and so on, and the electrolyte is close to saturation solubility in the solvent. It also includes solid electrolytes. With the continuous breakthrough of solid-state electrolytes in lithium-ion batteries, such electrolytes have become a research hotspot in the field of supercapacitor electrolytes.

The electrochemical performance of the supercapacitors
This section will briefly discuss the electrical performance of supercapacitors. It is hoped that analysis will reveal the causes of some special phenomena of supercapacitors and analyze the impact of these phenomena on the performance of capacitors. The following will also discuss how to choose the supercapacitor that matching different situation correctly, based on the requirements of different supercapacitor applications fields.

U is voltage and Q is charge

In addition to the influence of voltage on the capacitance of the supercapacitor, the ambient temperature also affects the capacitance of the supercapacitor. Although supercapacitors have a wide operating temperature range, wide temperature changes will have a certain impact on the capacitance of supercapacitors. As a part of energy storage tools, when designing the system, the impact of ambient temperature on the capacitance of supercapacitors should be fully considered. Temperature mainly affects the capacitance of supercapacitors by affecting the anion and cation Brownian motion on both sides of the electric double layer. Generally speaking, temperature affects different ion Brownian motions differently, which means that when the temperature increases, different anion and cation Brownian motion speeds increase. A larger gap will reduce the capacitor capacitance. Some studies have reported that when the temperature changes by 1°C, the capacitance of the supercapacitor will change by 0.1%, indicating that when the operating temperature of the supercapacitor changes by 80 ° C, there will be an 8% capacity change. Although the temperature change has little effect on the capacitance of the supercapacitor, it should be paid enough attention in the system design.

This process requires energy. The existence of the latter two holes will affect the electric double layer charge distribution. The charge distribution has a certain relationship with the fast rate of charging and discharging and the life of the capacitor.

The study found that it is precisely due to the existence of this solvation phenomenon that the supercapacitor cannot achieve full discharge under high power. It is reported that depolarized ions and dissolved polarized ions account for about 20% of the electrode surface area in commonly used capacitors.

The study has found that it is the existence of this solvation phenomenon that enable the supercapacitor to achieve full discharge under high power. It is reported that depolarized ions and dissolved polarized ions account for about 20% of the electrode surface area in commonly used capacitors.

Generally, the effect of temperature change on electrons and ions is opposite. For solid-state electrodes, when the temperature increases, the vibration of atoms in the solid molecules will be more intense, which will generate greater Joule heat. For ions, when the temperature increases, it will accelerate the molecule movements, reduces the viscosity, which is conductive to reduce the energy loss caused by the ion movement. Studies have shown that ion movement is affected by temperature more significantly, indicating that when the temperature is increased, it is beneficial to reduce the energy loss of the super capacitor.

Compared with other electrochemical energy storage technologies, the ohmic polarization has less effect on supercapacitors. Since the typical application scenario of supercapacitors is high power, this application scenario needs to pay attention to two aspects. On the one hand, the ohmic polarization of supercapacitors will cause significant voltage changes, which will affect efficiency. Since the most significant feature of supercapacitors is the higher efficiency, the ohmic polarization can be used as an important indicator to judge the performance of the product; on the other hand, during the use process, it is necessary to avoid the danger caused by excessive temperature, and good thermal management is required in the product design.

Ⅳ. Self-discharge
High self-discharge is one of the main disadvantages of supercapacitors, which greatly limits the application of supercapacitors. In practice, the product energy retention time is relatively short, and some researchers have found that the capacity loss rate is up to 36% after 2 hours of storage. The capacity loss of the supercapacitor is mainly caused by the leakage point flow formed by the ions in the supercapacitor through the electrolyte membrane. The self-discharge rate of the supercapacitor is linearly related to the storage time. The researchers reduced the self-discharge performance of the supercapacitor through electrode coating, but sacrificed the energy density of the supercapacitor.

Characteristics and Advantages of Supercapacitors(2021年)

kamcappower — 2021-11-24T15:03:09+0900

https://www.kamcappower.com/advantages-of-supercapacitor-ultra-capacitor.html

Supercapacitor, also known as electrochemical capacitor, double layer capacitor, gold capacitor, Farad capacitor, is an electrochemical component developed from the 1970s and 1980s to store energy through polarized electrolyte. Above is the supercapacitor definition. It is different from the traditional chemical power supply. It is a kind of power supply with special performance between the traditional capacitor and battery, mainly relying on double layer and redox pseudocapacitor charge storage of electrical energy. However, there is no chemical reaction during the energy storage process, which is reversible and types of supercapacitors can be recharged and discharged hundreds of thousands of times.

Supercapacitors are characterized by:
(1) Supercapacitors have fast charging speed, charging 10 seconds to 10 minutes can reach more than 95% of its rated capacity.
(2) Long cycle life, deep charging and discharging cycle times up to 1 ~ 500,000 times, no "memory effect".
(3) High current discharge capacity, high energy conversion efficiency, small process losses, high current energy cycle efficiency ≥ 90%.
(4) High power density, up to 300W/KG~5000W/KG, equivalent to 5~10 times of the battery.
(5) There is no pollution in the composition of raw materials, production, use, storage and dismantling process, which is an ideal green power supply.
(6) Simple charging and discharging circuits, no need for rechargeable batteries, high safety factor, long-term use and maintenance-free.
(7) Good ultra-low temperature characteristics, wide temperature range -40℃～+70℃.
(8) Convenient detection, with direct readout of remaining charge.
(9) Capacities typically range from 0.1F to 1000F.

As a new product in capacitors, the advantages of supercapacitors are significantly outweigh the disadvantages.

The advantages of supercapacitors are:

Electrical capacity
Early conventional capacitors had smaller capacitance storage capacity and could only meet the needs of small load circuits, while supercapacitors have a capacity class up to the Faraday level and are suitable for more complex circuit operation.

Circuits
Supercapacitors require less circuitry and do not require special charging and discharging control circuits, and the life of the capacitor is not affected by overcharging or overdischarging.

Welding
Soldering is not possible with conventional capacitors but can be done as required when installing supercapacitors, which prevents the occurrence of poor battery contact and improves the performance of capacitor components.

Environmental protection

It is a green energy source that is less polluting to the environment than other conventional capacitors.

How to Use a Supercapacitor Properly(2021年)

kamcappower — 2021-11-24T15:02:32+0900

https://www.kamcappower.com/products/

In applications where high reliability is required and energy requirements are not high, supercapacitors can be used instead of conventional batteries, or supercapacitors and batteries can be combined. Smaller and more economical batteries can be used in applications with high energy requirements.

Notice for using supercapacitors properly:
1. Supercapacitors have a fixed polarity. The polarity should be confirmed before use.
2. Supercapacitors should be used at the following nominal voltages. When the capacitor voltage exceeds the nominal voltage, it will cause the electrolyte to decompose, and the capacitor will heat up, reducing capacity, increasing internal resistance, shortening life, and in some cases, causing the capacitor to collapse.
3. Supercapacitors should not be used in high frequency charging and discharging circuits, high frequency rapid charging and discharging will lead to internal heating, capacity degradation, increased internal resistance, and in some cases will cause the performance of the capacitor to collapse.
4. Life of super capacitor: the external ambient temperature has an important effect on the life of the supercapacitor. Capacitors should be kept as far away from heat sources as possible.
5. Voltage drop when the ultracapacitor is used as a back-up power supply. Due to the large internal resistance of the supercapacitor, there is a voltage drop at the instant of discharge, ΔV = IR.
6. Ambient gases in use: supercapacitors should not be exposed to relative humidity greater than 85% or to toxic gases, as these conditions can cause corrosion of the leads and capacitor cases, resulting in circuit breakage.
7. Storage of Supercapacitors: supercapacitor should not be placed in a high temperature, high humidity environment, should be stored at a temperature of -30 + 50 ℃, relative humidity less than 60% of the environment, to avoid sudden temperature rise and fall, because this will cause damage to the product.
8. Supercapacitor on the use of double-sided circuit board: when supercapacitors are used on double-sided circuit boards, care must be taken that the connections do not pass through areas accessible to the capacitors, short-circuiting can occur due to the way the supercapacitor is installed.
9. When welding the capacitor on the circuit board, the capacitor shell should not be contacted with the circuit board, otherwise the welding material will penetrate into the capacitor threading holes, which will affect the performance of the capacitor.
10. Do not forcibly tilt or twist the capacitor after installing an ultracapacitor, as this will loosen the capacitor leads and cause performance degradation.
11. To avoid overheating the capacitor in the welding process. Overheating of the capacitor during soldering will reduce the service life of the capacitor, e.g. if the thickness of 1.6mm printed circuit board is used, the welding process should be 260℃, time not more than 5s.
12. Cleaning after welding. After the capacitors have been soldered, the circuit boards and capacitors need to be cleaned, as some impurities may cause the capacitors to short circuit.
13. When super capacitors are used in series: when an supercapacitor is used in series, there is a problem of voltage equalization between the individual capacitors. Simply connecting them in series can cause one or more of the individual capacitors to over-voltage, which can damage these capacitors and affect their overall performance. Therefore, when the capacitors are used in series, technical support from the manufacturer is required.

Difference between Capacitor and Supercapacitor(2021年)

kamcappower — 2021-11-24T15:01:47+0900

https://www.kamcappower.com/products/

Supercapacitor, also known as Electrical Doule-Layer Capacitor (EDLC), Gold Capacitor, Farad capacitor. The biggest difference between capacitor and supercapacitor is that supercapacitor is an electrochemical physical component, but does not react chemically itself, the supercapacitor has a particularly large storage capacity, reaching farad-level capacity. How do you increase the area of the two poles? Supercapacitors store energy by injecting electrolytes. Under the action of the electrode, the charge on the electrode surface will attract the heterogeneous ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, constituting a double layer capacitance.

Supercapacitors combine the physical characteristics of ordinary capacitors with many advantages that conventional capacitors and batteries cannot match:

1. Supercapacitors have a large Faraday-level electrical capacity, which is much larger than ordinary capacitors.
2. Supercapacitors can instantly release power nearly ten times higher than ordinary batteries, and will not be damaged.
3. The cycle life of charge and discharge is more than 100,000 times, which is one of the biggest advantages. Conventional batteries can only be recharged a few hundred times.
4. Supercapacitors can be used normally in an ambient temperature of 40 degrees to 60 degrees, the performance of traditional batteries will be greatly reduced in low temperature.
5. Super charge holding capacity, leakage is very small, traditional batteries need to be charged frequently to maintain the state.
6. Supercapacitors can charge rapidly, its speed is dozens of times faster than ordinary batteries, a few minutes can be full of electricity required for a car.
7. Supercapacitors will not inherently pollute the environment, truly maintenance-free, while traditional batteries are still polluting.

They are used in high power starting motors, such as those for large diesel engines or gas turbines, which require large transient currents. With conventional batteries, the life expectancy will be very short, but supercapacitors are perfectly suited to the task.

What Is Super Capacitor/Ultra Capacitor(2021年06月09日)

kamcappower — 2021-06-04T16:57:08+0900

https://www.kamcappower.com/products/high-temperature-super-capacitors/

Super capacitor has a very wide range of uses. Combined with high energy density materials such as fuel cells, Supercap provides fast energy release to meet high power requirements, so that fuel cells can be used only as energy sources. At present, the energy density of Super capacitor/ultra capacitor can reach as high as 20 kW/kg and has begun to occupy the market between traditional capacitors and batteries.

In applications requiring high reliability but not high energy requirement, Supercapacitor can be used to replace traditional batteries, or UltraCap can be combined with batteries, which can be used in situations requiring high energy, and smaller and more economical batteries can be used.

The ESR value of ultra capacitor is very low, so it can output more current and absorb large current quickly. Compared with chemical charging principle, Supercapacitor's working principle makes the product performance more stable, so the service life of ultracapacitor will be longer. Super capacitor/ultra capacitor is undoubtedly the most ideal power source for devices such as power tools and toys that need fast charging.

Some products are suitable for battery, Super capacitor/ultra capacitor hybrid systems. Super capacitor/ultra capacitor can avoid using large batteries to obtain more energy. For example, digital cameras in consumer electronics, the use of Super capacitor/ultra capacitor allows digital cameras to use cheaper alkaline batteries rather than expensive Li-ion batteries.

Super capacitor/ultra capacitor cell rated voltage ranges from 2.5 V to 2.7V, so it is necessary to use multiple Super capacitor/ultra capacitor cells in many applications. When connecting these units in series, the design engineer needs to consider the balance and charging between the units.

Super capacitor can maintain long service life without failure as long as it works within the specified operating parameters. Super capacitor will last longer than most other electronic components in any given application, which is why ultra capacitor is the best transmission device in harsh environments.

However, if used improperly, Super capacitor will also be damaged in advance, although there are not many reasons for the premature damage of ultra capacitor (the following items). Please note the following to ensure that the ultra capacitor in the system achieves the longest service life.

Working temperature: Super capacitor does not generate or provide power or energy through electrochemical reactions. Simply , it is achieved by static electricity. Obviously, electrochemical reactions in super capacitor are not only non-existent but also unnecessary. Higher temperature will catalyze the chemical reaction and accelerate the reaction rate. This applies equally to super caps because ultra capacitor is also a chemical system. Therefore, if we want to break down the service life of supercapacitor and let it work beyond the rated operating temperature range, it will surely rapidly attenuate its capacitance, increase its resistance at an unimaginable rate, and seriously reduce its efficiency. The magnitude of the damaging effect is proportional to the range and duration of overheating.

Working voltage: The electrochemical system generally has a stable working voltage range, beyond which the system will become unstable from the electrochemical point of view. As with overheating, the consequences of overvoltage include accelerated capacitance decline and accelerated resistance rise. Overpressure also increases the gas production rate of the monomer. If the overpressure is serious, the gas will increase to a certain extent, which will cause the internal pressure of the single body to be too large and rupture, and then immediately fail. Ultra cap, unlike some other electrochemical energy storage technologies, has no Undervoltage limitation. In fact, although the reverse voltage should not be applied, as long as the reverse voltage does not exceed the absolute value of the normal rated voltage, it will not destroy the supercaps or cause danger. Like temperature, the effect of overpressure depends on the magnitude and duration of overpressure.

Mechanical abuse: Let ultracapacitor work beyond the mechanical parameters (such as vibration or impact standards), except for the most robust structure, can not be immune. Sometimes it fails immediately.

The Supercapacitors: its Basic Principles, Classification, and its Electrical Performance(2021年06月07日)

Ⅰ. The working principle of the supercapacitor
As shown in Figure 1, the supercapacitor is mainly composed of many parts, like current collectors, electrodes, electrolytes, and separators. The role of the separator has the same function as the separator in the battery. It isolates the two electrodes to prevent short circuit between the electrodes and allows ions to pass through. The basic principle of supercapacitor energy storage is to store electrical energy through the electric double-layer capacitance formed by the charge separation on the interface between the electrolyte and the bath solution.
Ⅱ. The energy storage mechanism
There are many materials used in the manufacture and production of supercapacitor electrodes and electrolytes. In order to deeply understand the energy storage mechanism of supercapacitors and optimize the performance of supercapacitors, it is usually necessary to use two experiments, the cyclic voltammetry curve, and the constant current discharge to characterize the electrode performance of the different supercapacitor. Figure 2 shows two experiments, the cyclic voltammetry curve, and the constant current discharge of the supercapacitor, under different energy storage mechanisms, where a and c represent the cyclic voltammetry curve and the constant current discharge curve of the supercapacitor electrode, under the storage mechanism of electric double layer capacitance and pseudo capacitance, respectively; b and d respectively represent the cyclic voltammetry curve and constant current discharge curve of the supercapacitor electrode under the Faraday capacitor storage mechanism.
1. The storage mechanism of the electric double layer capacitor
The electric double layer effect is that the positive and negative charges should be separative, which are generated by the accumulation at the electrode-electrolyte interface. It is the main mechanism for energy storage of supercapacitors such as activated carbon, carbon fiber, carbon felt and other carbon materials. The formation of the electric double layer effect is mainly caused by the increase or decrease of high-energy conduction band electrons on the electrode surface, which causes the movement of positive and negative charges in the electrolyte solution on the interface side, which is used to balance the charge imbalance caused by the change of the high-energy conduction band electrons on the electrode surface.
Considering the charge density on the electrode surface is depended by the applied voltage, the electric double layer capacitance differs depending on the voltage. The electrochemical reaction in the electric double layer capacitor mainly occurs on the electrode surface, and it is usually the adsorption and desorption behavior of anions and cations. The cyclic voltammetry curve of the electric double layer capacitor has a rectangular shape as shown in Fig. 2 (a), and the constant current discharge curve of this type of material has a linear relationship, as shown in Fig. 2 (c).
The electric double layer effect occurs at the interface between the electronic conductor and the ionic conductor, which is present in almost all electrochemical energy storage systems. However, it is generally regarded as a side reaction in electrolyzers, fuel cells, and batteries, and it will not be regarded as the main energy storage mechanism. On the contrary, the working principle of supercapacitors is based on this effect, which requires supercapacitors to maximize this effect in the design and development process.

3. The Faraday reaction storage mechanism
This storage mechanism is mainly based on the redox reaction of metal cations in the electrode, usually accompanied by the redox reaction of metal cations. The extraction and insertion of metal cations in the electrode material phase extraction will cause the gain and loss of electrons in the material and then stores energy. It mainly includes two ways of material phase transformation or alloying reaction. When these electrodes are charged and discharged, a plateau voltage will appear, which corresponds to the redox peak voltage in the cyclic voltammogram, as shown in Figure 2 (b) and 2 (d). Compared with the other two types of capacitors, Faraday capacitance have higher stored energy, which is generally 10-100 times that of electric double layer capacitors.
Some electrode materials that exhibit Faraday effect, such as Ni (OH) 2 or similar battery electrode materials, are considered to be pseudocapacitive materials in many literatures, which is confusing to the readers. Although this type of material has a higher energy storage energy density and is limited by the solid phase diffusion of the material ions, the high-power charge-discharge performance is far worse than the pseudocapacitance material.

Ⅰ. The relationship between the voltage and the capacity
The variable capacity is one of the characteristics of supercapacitors, although this feature is not the most critical performance of supercapacitors. But when SC is part of the energy system, it needs to be considered. This is because the capacity variation of the supercapacitor in the entire voltage range is between 15% and 20% of the rated capacity, which cannot be ignored in most designs of energy systems. The capacitance of the supercapacitor can be measured by formula (1). The formula associates the charge and the voltage stored between the electric double layers, which indicates that the amount of charge stored between the electric double layers is proportional to the voltage. As the voltage increases, the charge distribution density near the electric double layer will become higher.
In addition to the influence of voltage on the capacitance of the supercapacitor, the ambient temperature also affects the capacitance of the supercapacitor. Although supercapacitors have a wide operating temperature range, wide temperature changes will have a certain impact on the capacitance of supercapacitors. As a part of energy storage tools, when designing the system, the impact of ambient temperature on the capacitance of supercapacitors should be fully considered. Temperature mainly affects the capacitance of supercapacitors by affecting the anion and cation Brownian motion on both sides of the electric double layer. Generally speaking, temperature affects different ion Brownian motions differently, which means that when the temperature increases, different anion and cation Brownian motion speeds increase. A larger gap will reduce the capacitor capacitance. Some studies have reported that when the temperature changes by 1°C, the capacitance of the supercapacitor will change by 0.1%, indicating that when the operating temperature of the supercapacitor changes by 80 ° C, there will be an 8% capacity change. Although the temperature change has little effect on the capacitance of the supercapacitor, it should be paid enough attention in the system design.

Ⅱ. The electrode surface charge distribution law
Usually, the supercapacitor has considered the matching performance between the size of the electrode pore and the size of the electrolyte in the design process. It should be pointed out that the supercapacitor electrolyte solvent is usually composed of polar molecules, such as water molecules, acetonitrile, etc. These polar molecules will solvate the ions and combine into larger and more stable units. When the diameter of the electrode pore is smaller than the diameter of the free ion, solvated ions and free ions will not pass through the hole and will not affect the electric double layer capacitance; when the pore is larger than the solvated ion, the solvated ion will pass through the hole; When the pores are between the diameter of ions and solvated ions, free ions will pass through the pores, and the solvated ions will be desolvated to form free ions into the pores.
This process requires energy. The existence of the latter two holes will affect the electric double layer charge distribution. The charge distribution has a certain relationship with the fast rate of charging and discharging and the life of the capacitor.
The study found that it is precisely due to the existence of this solvation phenomenon that the supercapacitor cannot achieve full discharge under high power. It is reported that depolarized ions and dissolved polarized ions account for about 20% of the electrode surface area in commonly used capacitors.
The study has found that it is the existence of this solvation phenomenon that enable the supercapacitor to achieve full discharge under high power. It is reported that depolarized ions and dissolved polarized ions account for about 20% of the electrode surface area in commonly used capacitors.

Ⅲ. The ohmic polarization
During charging and discharging, the ions and the electrons in the supercapacitor will have some movements. On the one hand, due to the Joule heat generated by the movement of electrons, it will convert the kinetic energy of the electrons into heat energy, which will dissipate through the conductor. On the other hand, the ions will be rubbed with other ions during the movement of the electrolyte to generate heat. The voltage which offsets these two energy consumptions is proportional to the transport ion or current, and this phenomenon is called the ohmic polarization phenomenon of supercapacitors.
Generally, the effect of temperature change on electrons and ions is opposite. For solid-state electrodes, when the temperature increases, the vibration of atoms in the solid molecules will be more intense, which will generate greater Joule heat. For ions, when the temperature increases, it will accelerate the molecule movements, reduces the viscosity, which is conductive to reduce the energy loss caused by the ion movement. Studies have shown that ion movement is affected by temperature more significantly, indicating that when the temperature is increased, it is beneficial to reduce the energy loss of the super capacitor.
Compared with other electrochemical energy storage technologies, the ohmic polarization has less effect on supercapacitors. Since the typical application scenario of supercapacitors is high power, this application scenario needs to pay attention to two aspects. On the one hand, the ohmic polarization of supercapacitors will cause significant voltage changes, which will affect efficiency. Since the most significant feature of supercapacitors is the higher efficiency, the ohmic polarization can be used as an important indicator to judge the performance of the product; on the other hand, during the use process, it is necessary to avoid the danger caused by excessive temperature, and good thermal management is required in the product design.

How to Use a Supercapacitor Properly(2021年06月05日)

kamcappower — 2021-06-04T16:54:47+0900

https://www.kamcappower.com/products/

Notice for using supercapacitors properly:

1. Supercapacitors have a fixed polarity. The polarity should be confirmed before use.

2. Supercapacitors should be used at the following nominal voltages. When the capacitor voltage exceeds the nominal voltage, it will cause the electrolyte to decompose, and the capacitor will heat up, reducing capacity, increasing internal resistance, shortening life, and in some cases, causing the capacitor to collapse.

3. Supercapacitors should not be used in high frequency charging and discharging circuits, high frequency rapid charging and discharging will lead to internal heating, capacity degradation, increased internal resistance, and in some cases will cause the performance of the capacitor to collapse.

4. Life of supercapacitors: the external ambient temperature has an important effect on the life of the supercapacitor. Capacitors should be kept as far away from heat sources as possible.

5. Voltage drop when the ultracapacitor is used as a back-up power supply. Due to the large internal resistance of the supercapacitor, there is a voltage drop at the instant of discharge, ΔV = IR.

6. Ambient gases in use: supercapacitors should not be exposed to relative humidity greater than 85% or to toxic gases, as these conditions can cause corrosion of the leads and capacitor cases, resulting in circuit breakage.

7. Storage of Supercapacitors: supercapacitor should not be placed in a high temperature, high humidity environment, should be stored at a temperature of -30 + 50 ℃, relative humidity less than 60% of the environment, to avoid sudden temperature rise and fall, because this will cause damage to the product.

8. Supercapacitor on the use of double-sided circuit board: when supercapacitors are used on double-sided circuit boards, care must be taken that the connections do not pass through areas accessible to the capacitors, short-circuiting can occur due to the way the supercapacitor is installed.

9. When welding the capacitor on the circuit board, the capacitor shell should not be contacted with the circuit board, otherwise the welding material will penetrate into the capacitor threading holes, which will affect the performance of the capacitor.

10. Do not forcibly tilt or twist the capacitor after installing an ultracapacitor, as this will loosen the capacitor leads and cause performance degradation.

11. To avoid overheating the capacitor in the welding process. Overheating of the capacitor during soldering will reduce the service life of the capacitor, e.g. if the thickness of 1.6mm printed circuit board is used, the welding process should be 260℃, time not more than 5s.

12. Cleaning after welding. After the capacitors have been soldered, the circuit boards and capacitors need to be cleaned, as some impurities may cause the capacitors to short circuit.

13. When super capacitors are used in series: when an supercapacitor is used in series, there is a problem of voltage equalization between the individual capacitors. Simply connecting them in series can cause one or more of the individual capacitors to over-voltage, which can damage these capacitors and affect their overall performance. Therefore, when the capacitors are used in series, technical support from the manufacturer is required.

Difference between Capacitor and Supercapacitor(2021年06月04日)

kamcappower — 2021-06-04T16:54:12+0900

https://www.kamcappower.com/products/

Supercapacitor, also known as Electrical Doule-Layer Capacitor (EDLC), Gold Capacitor, Farad capacitor. The biggest difference between capacitor and supercapacitor is that supercapacitor is an electrochemical physical component, but does not react chemically itself, the supercapacitor has a particularly large storage capacity, reaching farad-level capacity. How do you increase the area of the two poles? Supercapacitors store energy by injecting electrolytes. Under the action of the electrode, the charge on the electrode surface will attract the heterogeneous ions in the surrounding electrolyte solution, causing these ions to attach to the electrode surface to form a double charge layer, constituting a double layer capacitance.

Supercapacitors combine the physical characteristics of ordinary capacitors with many advantages that conventional capacitors and batteries cannot match:

1. Supercapacitors have a large Faraday-level electrical capacity, which is much larger than ordinary capacitors.

2. Supercapacitors can instantly release power nearly ten times higher than ordinary batteries, and will not be damaged.

3. The cycle life of charge and discharge is more than 100,000 times, which is one of the biggest advantages. Conventional batteries can only be recharged a few hundred times.

4. Supercapacitors can be used normally in an ambient temperature of 40 degrees to 60 degrees, the performance of traditional batteries will be greatly reduced in low temperature.

5. Super charge holding capacity, leakage is very small, traditional batteries need to be charged frequently to maintain the state.

6. Supercapacitors can charge rapidly, its speed is dozens of times faster than ordinary batteries, a few minutes can be full of electricity required for a car.

7. Supercapacitors will not inherently pollute the environment, truly maintenance-free, while traditional batteries are still polluting.

Solar Energy(2020年02月26日)

kamcappower — 2020-02-21T17:27:05+0900

http://www.kamcappower.com/super-capacitor-ultracapacitor-solar-energy.html

The solar supercapacitor applications come down to two aspects of solar energy utilization and solar energy utilization. Solar power generation is divided into photovoltaic power generation and solar thermal power generation, in which photovoltaic power generation uses photovoltaic cells to directly convert solar energy into electrical energy. Photovoltaic power generation is far stronger than CSP in terms of conversion efficiency, equipment cost and development prospects. Since the advent of practical polycrystalline silicon photovoltaic cells, the world has begun to use solar photovoltaic power generation.

At present, solar supercapacitor systems have three development directions: independent operation, grid-connected and hybrid photovoltaic power generation systems. In an independent operating system, the energy storage unit is generally required to store the remaining electrical energy emitted by the sun for insufficient sunshine or no sunshine. At present, the demand of the international photovoltaic energy industry has begun to develop from the remote rural areas and special applications to the grid-connected power generation and construction combined power supply. supercapacitors for solar energy storage has the transition from supplementary energy to alternative energy. The domestic photovoltaic energy system is still mainly used in remote and non-electric areas and urban street lights, lawn lights, garden lights, billboards and other independent photovoltaic power generation systems. Through the energy storage system composed of battery packs, it can smooth the fluctuation of electric energy caused by fluctuations in solar light intensity, and can also compensate for voltage dips or sudden rises in the grid system, but due to its limited number of charge and discharge, high current charge and discharge time is slow. And other factors, so its short life and high cost. Therefore, the use of ultra-capacitor banks in solar photovoltaic power generation systems will make grid-connected power generation more feasible.
