Lithium iron phosphate battery refers to a lithium ion battery that uses lithium iron phosphate as a positive electrode material. The battery cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries. In terms of material principle, lithium iron phosphate is also an intercalation and deintercalation process, which is exactly the same as lithium cobaltate and lithium manganate.

1. Improvement of safety performance

The P-O bond in the lithium iron phosphate crystal is stable and difficult to decompose. Even at high temperature or overcharge, it will not collapse and generate heat like lithium cobalt oxide or form strong oxidizing substances, so it has good safety.

2 Improvement of life expectancy

The cycle life of long-life lead-acid batteries is about 300 times, and the maximum is 500 times, while the cycle life of lithium iron phosphate power batteries can reach more than 2,000 times, and the standard charging (5-hour rate) can reach 2,000 times.

3. Good high temperature performance

The electric heating peak of lithium iron phosphate can reach 350℃-500℃, while lithium manganate and lithium cobaltate are only around 200℃.

4. Large capacity

Has a larger capacity than ordinary batteries (lead acid, etc.). The monomer capacity is 5AH-1000AH.

5. No memory effect

Rechargeable batteries often work under the condition of being fully charged, and the capacity will quickly drop below the rated capacity. This phenomenon is called memory effect.

6. Light weight

The volume of the lithium iron phosphate battery with the same specification and capacity is 2/3 of the volume of the lead-acid battery, and the weight is 1/3 of the lead-acid battery.

7. Environmental protection

Lithium iron phosphate batteries are generally considered to be free of heavy metals and rare metals (nickel-metal hydride batteries require rare metals), non-toxic (SGS certification), non-polluting, comply with European RoHS regulations, and are green batteries.
