Lithium iron phosphate (LiFePO4) battery refers to a lithium ion battery which using lithium iron phosphate as a positive electrode material. Lithium-ion battery cathode materials include lithium cobalt oxide, lithium manganese oxide, lithium nickelate, ternary materials, and lithium iron phosphate. Among them, lithium cobalt oxide is the cathode material used in most lithium-ion batteries.

The advantages of LiFePO4 battery as below:

1.  Cycle life up to 2000 times or more,

2.  Wide working temperature (-20°C~75°C), good performance in high temperature,

3.  Have no memory effect, the battery can be charged and used no matter what state it is in, and it is not necessary to wait the power runs out and then charge for it.

4.  Light weight, the volume of the LiFePO4 battery is 2/3 of the lead-acid battery in the same specifications capacity, the weight is 1/3 of the lead-acid battery,

5.  Good safety performance, without any heavy metals and rare metals, non-toxic, no pollution, in line with European RoHS regulations, is a green battery.

LiFePO4 batteries also have the disadvantages of poor performance in low temperature, low tap density of positive electrode materials, and the volume of LiFePO4 batteries are larger than lithium cobalt oxide lithium-ion battery, so there is no advantage in terms of miniature batteries. When used in power batteries, LiFePO4 batteries, like other batteries, need to face battery consistency problems.

LiFePO4 batteries are widely used in electric vehicles, power tools, solar & wind power energy storage equipment, UPS and emergency lights, warning lights and miner's lamps, small medical equipment and portable instruments and other fields.
