Lithium iron phosphate electrode materials are mainly used for various lithium ion batteries

The main applications of lithium iron phosphate are as follows:

A storage device

The energy storage equipment of solar energy and wind power system is UPS, which is used as energy storage equipment (BYD is already producing such batteries).

The electric tool

High power electric tools (wireless), electric drills, weeding machines, etc.

The light electric vehicle

Electric motor cars, electric bicycles, recreational cars, golf carts, electric pushing machines, cleaning cars, hybrid electric vehicles (HEV) have been targeted for nearly 2-3 years.

The small device

Medical equipment: electric wheelchair car, electric step car), toys (telecontrol electric aircraft, car, ship);

High energy density,

Its theoretical specific capacity is 170 mAh/g, and the actual specific capacity of the product can exceed 140 mAh/g (0.2C, 25 C).

Security,

It is the most safe cathode material for lithium ion batteries at present; it does not contain any heavy metal elements that are harmful to the human body.

Long life:Under 100%DOD conditions, charge and discharge can be more than 2000 times. (cause: lithium iron phosphate has good lattice stability, and the insertion and withdrawal of lithium ion has little effect on the lattice, so it has good reversibility. The deficiency is that the conductivity of the electrode is poor, which is not suitable for the charge and discharge of large current, and is hindered in application. The solution: coating the conductive material on the surface of the electrode and modifying the electrode.)

The service life of LiFePO4 battery is closely related to its service temperature. The low or too high temperature of the LiFePO4 will cause great potential risks in its charging and discharging process and operation process. Especially in the electric cars in the north of China, in the autumn and winter, the lithium iron phosphate battery can not supply normally or the power supply is too low, so it needs to adjust its working environment temperature and maintain its performance. At present, the problem of space limitation must be taken into account in solving the constant temperature working environment of lithium iron phosphate battery in China. The general solution is aerogel blanket as insulation layer.
