The layered rock-salt structural materials, LiMO (M=Ni, Co, etc.) are promising candidates as cathodes in rechargeable lithium-ion batteries. These materials are defective in their electrochemical properties because their structures and thermal propertiesare unstable during the lithium (de)intercalation process. However, the substituted Li(Ni,Co,Al)O system shows the good electrochemical and thermal properties. The Mg doped system, Li(M,Mg)O, also shows good cycle stabilities. In this study, the effect of Mg doping into the Li(Ni,Co,Al,Mg)O system was studied with Mg compositions between 0 Mg 0.1. In this presentation, the detailed structure will be discussed.
