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 large-scale commercial applications in the future.
