Cathode material is one of the 4 key materials of Lithium-ion battery (LIB), which accounts for 30~40% manufacturing costs of LIB, and it is also a key material to determine the safety, performance, cost and life of the battery. LIB cathode materials mainly include LiCoO2 (LCO), Li M2O4 (LMO), NCM, LiFePO4 (LFP) etc.; each has self characteristics and good applications. Due to the differentiated needs of various applications, the diversified cathode materials technologies will be coexist and
