LiFePO4 Powder Raw Materials For Lithium ion Battery Producing
Specification
Main application: Is the positive active material of the power battery. Mainly used for energy storage/electric tools/light electric vehicle/miner's lamp/mobile power and so on.
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.
