Abstract：The lithium rich manganese based material x Li2MnO3·(1-x) LiMO2 (M=Ni,Co,Mn,Zr,etc.) is a layered structure of lithium-ion cathode material,which has attracted much attention for its high reversible specific capacity (>250 mAh/g) and low watt hour cost.The material has been successfully applied in different scenarios,commonly used as pure cathode material (preferred cathode material for solid-state batteries),a mixed type (mixed with lithium manganese oxide,lithium manganese iron phosphate,etc.),and a positive electrode lithium supplement agent.The synthesis methods of lithium-rich manganese based materials are diverse,mainly including sol-gel method,coprecipitation method,polymer pyrolysis method,hydrothermal method and solid phase method.Among them,coprecipitation method has a mature process and a relatively high degree of industrialization.Due to their continuous innovation and upgrading of performance,the promising prospect of lithium-rich manganese-based cathode materials is expected to develop towards largescale commercial applications in the future.
