Lithium iron phosphate battery

Lithium iron phosphate electrode materials are mainly used for various lithium ion batteries. Since 1996, NTT of Japan revealed for the first time the lithium battery anode material of olivine structure of AyMPO4 (A is an alkali metal, M is a combination of both CoFe and LiFeCoPO4), and John B. Goodenough of Texas State University in 1997. Other research groups also reported the characteristics of LiFePO4 reversibly migrating in and out of lithium. The United States and Japan issued an olivine structure (LiMPO4) invariably, which made the material highly valued and caused extensive research and rapid development. development of. Compared with traditional lithium ion secondary battery cathode materials, spinel LiMn2O4 and layered LiCoO2, LiMPO4 has a wider source of raw materials, lower cost and no environmental pollution.
