What is Lithium Titanate Battery?

Lithium titanate battery is a lithium titanate used as a negative electrode material for lithium ion batteries. It can be combined with lithium manganate, ternary materials or lithium iron phosphate to form a 2.4V or 1.9V lithium ion secondary battery. In addition, it can also be used as a positive electrode to form a 1.5V lithium secondary battery with metallic lithium or lithium alloy negative electrode.

Advantages of Lithium Titanate Battery:

1. First of all, the charging speed is amazing

Under the condition of high-rate charging, the lithium titanate battery needs only 6 minutes to fully charge, while the ordinary ternary lithium battery and lithium iron phosphate battery also need 1-2 hours at the fastest. Increasing the speed by nearly ten times, it is almost like a bicycle turning into an airplane.

2. More than that, the cycle life of lithium titanate batteries is very high

Ordinary ternary lithium batteries have only more than 1,000 cycles. Lithium iron phosphate batteries are slightly better. BYD's blade batteries can achieve 3,000 cycles of cycle life, while lithium titanate batteries can reach tens of thousands of cycles.

3.These are not the biggest advantages of lithium titanate batteries, because its real advantages are safety and durability.

Lithium iron phosphate batteries and ternary lithium batteries usually have a large attenuation around -20°C, while lithium titanate batteries can work normally in a low temperature environment of -50°C, which is better than other lithium batteries.

More importantly, the lithium titanate battery is safe. In the experiments of acupuncture, electric drill, cutting, burning, etc., there was no fire or explosion.

It can be said that once lithium titanate batteries become popular, it will rewrite the history of human energy storage!

But why did lithium titanate batteries not become mainstream? The main reasons for this phenomenon are as follows:

1. The life and performance of lithium batteries are affected by many aspects, especially the four major materials. Lithium titanate is only a negative electrode material, no matter how advanced a material is, it is difficult to give the product an unmatched advantage. What's more, the cathode material is the most important material that affects the performance of lithium batteries.

2. The biggest disadvantage of lithium titanate battery is its low energy density and high cost. In particular, the low energy density is due to the principle and performance of the anode material lithium titanate, and it is difficult to have a big breakthrough. Cost can be reduced through scale, but based on the weakness of the principle, it cannot be changed through technology.

3. As for the claimed long service life of lithium titanate batteries, it is more difficult to be certified. The battery life is also affected by the combination of cathode material, electrolyte, separator, and operating temperature.

Lithium titanate used as a negative electrode itself also has problems such as flatulence and reduced consistency in long-term use. At present, it is impossible to prove that too acid lithium batteries will have a longer life than other batteries in principle.

At present, the cycle life of lithium iron phosphate and ternary batteries can be more than 2000 times. According to the general frequency of use, it has been able to do 7-10 years. With the advancement of technology, there will be 3000 times and 4000 times. Even if the lithium titanate battery achieves a long life, it has no advantage.

4. There are few companies doing lithium titanate batteries, which will result in low overall R&D investment in the industry. Judging from the current R&D investment and planning investment of battery companies, few companies will focus on the development of lithium titanate batteries. In the future, other lithium battery technologies will advance faster than lithium titanate batteries.

Although the external controversy on lithium titanate batteries has not stopped, the controversy is not a bad thing. Let different voices be fully expressed, and the truth can be more and more clear.

What is battery cells? Difference between battery cell and battery Pack(2022年)

weislee — 2022-11-12T13:01:13+0900

https://www.ecolithiumbattery.com/product-category/battery-cells/

Compared with battery pack or module, the manufacturing of battery cell is two completely different industrial processes. Battery production is mainly a chemical process, while module and component production is a mechanical assembly process.

Batteries are sometimes referred to as batteries, modules, or battery packs. But what does that mean? What's the difference?

Batteries are containers for chemical storage of energy. They have a variety of shapes and forms, but the most common three are prismatic, bag and cylindrical.

The battery units are arranged in modules to achieve a serviceable unit. The battery is connected to the battery pack in series and parallel to achieve the required voltage and energy capacity. For example, electric vehicles require 400-800 volts, and a single battery usually has 3-4 volts.

Finally, the battery pack is the complete enclosure that supplies power to the electric vehicle. The battery pack usually contains battery cells and/or modules, software (BMS Battery Management System), and cooling and heating systems, depending on where and how the battery pack is used.

But, hold on, soon, you don't even need to know The battery will be directly integrated into the entire battery pack without dividing it into separate modules (battery to battery pack) or directly integrated into the chassis (battery to chassis).

Lithium Ion Battery
Lithium-ion batteries, also known as lithium-ion batteries, are the newest of the three main types. They are rechargeable batteries commonly used in portable electronics. For example, the battery in a cell phone is a lithium-ion battery.

While lithium-ion batteries are the most expensive of the three, they tend to pay for themselves quickly, which is their main advantage. Premium Li-Ion batteries can be charged twice as often as NiMH batteries.

Another advantage of lithium-ion batteries is constant power output. There is no loss of performance when the battery is discharged. Lithium-ion batteries also charge very quickly; typically within 1-3 hours. The icing on the cake is that Li-Ion batteries are 30% lighter than Alkaline and NiMH batteries, making them ideal for portability. What is a lithium-ion battery?
Lithium-ion is the most popular rechargeable battery chemistry today. Lithium-ion batteries power the devices we use every day, such as our cell phones and electric cars.

Lithium-ion batteries consist of single or multiple lithium-ion batteries and a protective circuit board. Once one or more battery cells are installed in a device with a protective circuit board, they are called a battery.

What are the components of a lithium-ion battery?

Electrodes: The positively and negatively charged ends of a cell. connected to the collector
Anode: Negative
Cathode: Positive
Electrolyte: Conductive liquid or gel
Current collectors: Conductive foils on each electrode of the battery, connected to the terminals of the battery. Battery terminals carry current between the battery, the device, and the energy source that powers the battery
Separator: A porous polymer film that separates electrodes while allowing lithium ions to be exchanged from one side to the other

How do lithium-ion batteries work?
In a lithium-ion battery, lithium ions (Li+) move internally between the cathode and anode. Electrons move in opposite directions in an external circuit. This migration is what makes the battery power the device—because it draws current.

As the battery discharges, the anode releases lithium ions to the cathode, creating a flow of electrons that helps power related devices.

When the battery is charged, the opposite happens: Lithium ions are released by the cathode and received by the anode.

FAQ - LIFEPO4 BATTERIES(2022年)

weislee — 2022-11-05T17:58:39+0900

https://www.ecolithiumbattery.com/product-category/lifepo4-batteries/

With the advantage of super long cycle life, ELB has provided innovative LiFePO4 batteries solutions for all kinds of application.

The special batteries provides high -circulation life and excellent performance at a wide range of working temperature.

The LiFePO4 battery is the safest lithium battery type in the market. Compared with sealing lead acid, the nominal voltage of the LiFePO4 battery are range from 3.2V to 500V, and the capacity are range from 2Ah to 280Ah.

What is LiFePO4 battery?
LiFePO4 batteries also called LFP batteries, which are a type of lithium battery also. Since the batteries are using lithium iron phosphate as the positive electrode material, so it is called LiFePO4 batteries.

LiFePO4 batteries is now known as the safest, most stable and most reliable lithium battery.

Benefits of LiFePO4 battery?

Lightweight And Compact
The electrodes (lithium and carbon) commonly used in LiFePO4 batteries are inherently light. Making them smaller and lighter than older batteries such as lead-acid batteries. For comparison, a typical 100Ah (= amp hour) Li-Ion battery weighs about the same as a 40Ah lead-acid battery (about 10-12kg). But has more than twice the capacity.

100% Depth Of Discharge (DOD)
Maximize your energy potential with 100% Depth of Discharge. This means that you can use 100% of the battery’s capacity to power your specific needs. Horever, Lead-acid/ AGM batteries slowly decrease their power and performance while the charge depletes.

High Energy Density
Lithium has the ability to release and store large amounts of energy. Enabling lithium iron phosphate batteries to package high energy capacity in a small size. This means that a lithium battery of the same weight will last much longer between charges than other rechargeable batteries. While still maintaining its high level of performance.

Low Maintenance
Older rechargeable battery types, such as nickel-cadmium or nickel-metal hydride batteries, have what’s called the “memory effect” or “inert cell effect”. If repeatedly partially discharged before charging, the final battery can only supply locally before the voltage drops. Energy used during discharge. To avoid this, NiCd and NiMH batteries need to be fully discharged and recharged on a regular basis for maintenance.

LiFePO4 batteries don’t suffer from memory effect, which means they always use up the last bit of charge. Whether you’re using 100% or 25% capacity, you can charge them without tedious maintenance!

Long Lifespan
High-quality lithium iron phosphate batteries last for about 4000 full charge cycles. A full charge cycle is when the battery is discharged to depletion and then charged to full, so using the battery until it reaches 75% capacity and then plugging it in to charge does not constitute a full charge cycle. When your battery is recharged, you can still use 75% of the charge remaining before charging; only then can your battery complete a full charge cycle.

Low Self-discharge Rate
Lithium batteries also have relatively low self-discharge rates. Self-discharge is a natural, irreversible phenomenon for batteries, where chemical reactions inside the battery reduce the capacity of the battery, even when the battery is not being used. The self-discharge rate of Li-ion batteries peaks at around 3% in the first 24 hours after charging, and then gradually decreases to 1-2% per month. In comparison, nickel-based rechargeable batteries lose about 10-15% of their capacity after charging, and another 10-15% per month.

How does LiFePO4 battery work?
While the battery is discharging and providing an electric current, the anode releases lithium ions to the cathode, generating a flow of electrons from one side to the other.

When plugging in the device, the opposite happens: Lithium ions are released by the cathode and received by the anode.

This process creates an electrical current that powers the electronic devices.

How to charge lithium iron phosphate LiFePO4 batteries?
After you get the right charger, charging your battery is a cinch. Here’s what to do, step by step:

1. Make sure the battery terminals are clean. Remove any grease and dirt.

2. First, connect the red (positive) cable to the red terminal. Then connect the black (negative) cable to the black terminal. Make sure cables are tightly connected to the battery terminals.

3. Plug in the charger. And switch on.

4. If using a smart charger, you can “set it and forget it”. It will stop charging on its own. Most lead acid chargers require setting a timer and disconnecting the charger when the battery is charged. But for lithium batteries, it is not necessary since there are BMS protection function.

5. To disconnect, unplug the charger. Remove the black cable, then the red one.
