With inorganic salts such as LiNO₃, Li₂CO₃, surface-coated LiMn₂O_3.95F_0.05 were prepared by melt-impregnation method. When these surface-coated LiMn₂O_3.95F_0.05 were used as cathode materials, their charge-discharge characters were carefully compared. As a result, they exhibited good charge-discharge properties at 50℃ high temperature. Especially, LiNO₃ surface-coated LiMn₂O_3.95F_0.05 retained nearly 80% initial reversible capacity after 130 cycles at 50℃.
