What is lithium iron phosphate
Lithium iron phosphate is an inorganic compound
It belongs to the orthorhombic olivine structure and the space group is Pnma
Lithium iron phosphate is used as a cathode material for lithium-ion batteries
Its theoretical specific capacity is 170mAh/g, the actual specific capacity of the product can exceed 140mAh/g
Mainly used in power batteries (HEV,EV, power tools)
Crystal structure of lithium iron phosphate
Advantages of lithium iron phosphate
The raw materials are abundant and cheap
> Environmentally friendly, does not contain any harmful heavy metal elements
Good thermal stability
Good cycle performance (can charge and discharge more than 2000 times under 100%DOD conditions)
Good thermal stability
o Thermal stability of LiFePO4 and FePO4 after charging
The sex is very good, FePO4 in 210~410°C temperature
The heat released in the range of degrees is only 210J/g
o LiCoO₂ Charging state (CoO2) begins to decompose
Oxygen is produced at a temperature of 240 ° C and heat is emitted
It’s about 1000J/g
Good cycle performance
Because LiFePO4 is structurally similar to FePO4, lithium ion
After removal/embedding, the LiFePO4 crystal structure is almost unchanged
Give birth to rearrangement.
Application of lithium iron phosphate
Due to the inherent structural stability of lithium iron phosphate,
Especially in terms of security and loop performance
With incomparable advantages,
So the use of lithium iron phosphate cathode material battery
It can be widely used in many fields.
