The advantages of lithium iron phosphate battery

The left side of the lithium iron phosphate battery is a positive electrode composed of LiFePO4 material of olivine structure, which is connected to the positive electrode of the battery by aluminum foil. On the right is the negative electrode of the battery made of carbon (graphite), which is connected to the negative electrode of the battery by copper foil. In the middle is the polymer separator, which separates the positive electrode from the negative electrode. Lithium ions can pass through the separator and electrons cannot pass through the separator. The battery is filled with electrolyte, and the battery is hermetically sealed by a metal casing.

Lithium Iron Phosphate Battery

The advantages of lithium iron phosphate battery:

1. High rate discharge

When the test temperature is 25°C and the test voltage is 2.9-3.3V, the discharge capacity of the lithium iron phosphate battery pack is close to 100% when the discharge voltage is close to 2.0V under different test voltages and rates.

2. High energy density

The weight energy density of the lithium battery pack is 150Wh/kg. At the same volume, the energy density of lithium-ion batteries is about 3-4 times that of lead-acid batteries. Compared with lead-acid batteries, lithium iron phosphate batteries of the same capacity have a weight reduction of about 60% to 70%.

3. High security

The electrochemical performance of the positive electrode material of lithium iron phosphate battery is relatively stable, which determines that it has a stable charge and discharge platform, therefore, the structure of the battery will not change during the charge and discharge process, will not burn and explode, and even in short circuit, excessive Under special conditions such as charging, squeezing and acupuncture, it is still very safe.

4. Long cycle life

The 1C cycle life of lithium iron phosphate batteries is generally 2000 times, or even more than 3500 times, and the energy storage market requires more than 4000-5000 times, which guarantees a service life of 8-10 years, which is more than 1,000 cycles of ternary batteries. The life cycle of long-life lead-acid batteries is about 300 times. These data are the results of testing through the battery cycle life tester.

5. Safety and environmental protection

Lithium iron phosphate batteries do not contain any heavy metals and rare metals, are safe, non-toxic and non-polluting, and are absolutely green and environmentally friendly batteries. Because the lithium iron phosphate material is clean and non-toxic throughout the production process, all raw materials are non-toxic and non-polluting.
