99.9% Purity LiFePO4 Powder for Power Battery Material      


Main characteristics:

1. High energy density, Its theoretical specific capacity is 170 mAh/g, Actual product specific capacity can be more than 140 mAh/g (0.2 C, 25 ° C);

2. High security, is the safety of lithium ion battery cathode material; Do not contain any harmful heavy metals;

3. long life: In 100% DOD (depth of discharge) conditions, can charge and discharge more than 2000 times; (reason: lithium iron phosphate lattice stability is good, the lithium ions embedded and emergence of lattice impact is not big, so it has good reversibility. The deficiencies are ionic conductivity electrode is poor, not suitable for large current charge and discharge, stuck in applications. Solution: in the electrode coating on the surface of conductive material, doped modified electrode. )

 

The service life of the lithium iron phosphate battery with temperature, temperature too low or too high in the charging and discharging process and use process produce greatly bad hidden trouble. Electric cars use especially in northern China, in the fall and winter normal power supply of the lithium iron phosphate batteries or power supply is too low, need to adjust its working environment temperature to maintain its performance. At present, the domestic solve the lithium iron phosphate battery temperature working environment should be considered space limitations, the common solution is to use the aerogel blanket as a thermal insulation layer.
