제목 Core-shell structure with improved Initial Coulombic Efficiency that can control number density of Si particles through Organic/Inorganic polymerization
초록 A core-shell structure having desgined void spaces is introduced in Li ion battery fields for solving problems of Si based anodes. The Core-shell structure shows stable cycle life and electrcial conductivity than bare si anode. But this structure showed low initial columbic efficiency because of large surface areas. In this work, we introduce a high density Si embedded core-shell structure through organic/inrganic polymerization. The Si embedded core-shell structure showed higher initial columbic efficiency about 80% than single core-shell strcuture. we expect our design process for confining active materials inside the shell to be applicable to other materials that can eventually be used as high-performance anodes for the next generation LIBs.
