Features of lithium iron phosphate lifepo4 battery



lithium iron phosphate



(1) High energy density  

The theoretical specific capacity of lithium iron phosphate LiFePO4 is 170mAh/g, and the actual specific capacity of the product can exceed 140mAh/g (0.2C, 25 íŠ); 

(2) Security 

Lithium iron phosphate is the safest cathode material for lithium-ion batteries. Does not contain any heavy metal elements harmful to the human body; 

(3) Long life 

Under 100%DOD condition, it can charge and discharge more than 2000 times; (Reason: lithium iron phosphate crystal has an excellent stable performance, and lithium-ion embedment and release have little impact on the lattice has good reversibility. The deficiency is that the electron-ion transfer rate is poor, unsuitable for high current charge and discharge, blocked in the application. Solution: The electrode surface was coated with a conductive material and doped to modify the electrode. 

(4) No memory effect 

(5) Charging performance 

The lithium-ion battery, which uses lithium iron phosphate as the cathode material, can be charged at a high rate and fully in as little as one hour.
