LFP cathode materials lithium iron phosphate battery refers to lithium iron phosphate(LFP) as the cathode material of lithium ion battery. There are many kinds of cathode materials for lithium ion batteries. Including lithium cobalt, lithium manganese, lithium nickel, ternary materials, lithium iron phosphate and so on. Lithium iron phosphate (LFP, LiFePO4) cathode material is mainly used in various lithium ion batteries.
Lithium phosphate has good electrochemical performance and low resistance. LFP cathode material concentrates the advantages of LiCoO2, LiNiO2, LiMn2O4 and their derivatives: The raw material of lithium iron phosphate cathode material is more extensive, cheaper and no environmental pollution; The operating voltage of LFP battery is moderate (3.4V); Large theoretical capacity (170mAh/g); Stable structure, excellent safety performance; The high temperature performance and thermal stability are obviously better than other known cathode materials; Good cycling performance, volume reduction when charging, with carbon anode material with good volume effect; Good compatibility with most battery electrolyte systems, good storage performance, non-toxic, it is truly environmentally friendly material.
LFP cathode material(LiFePO4) has outstanding advantages in cost, high temperature performance and safety comparing with LiCoO2, LiNiO2, LiMn2O4 and their derivative cathode materials. It has become the preferred cathode material for large capacity, high power lithium ion batteries.
The industrialization and popularization of the material is of great significance to reduce the cost of lithium ion battery, improve battery safety, expand the lithium ion battery industry, and promote the large-scale and high-power lithium ion battery.
