摘要
With inorganic salts such as LiNO3, Li2CO3, surface-coated LiMn2O3.95F0.05 were prepared by melt-impregnation method. When these surface-coated LiMn2O3.95F0.05 were used as cathode materials, their charge-discharge characters were carefully compared. As a result, they exhibited good charge-discharge properties at 50oC high temperature. Especially, LiNO3 surface-coated LiMn2O3.95F0.05 retained nearly 80% initial reversible capacity after 130 cycles at 50oC.
