Abstract
A battery material is a core-shell structure, and the core-shell structure includes a core and a shell. The shell surrounds the core. A composition of the core is a silicon material. The shell includes a polymer, the polymer is linear, the polymer includes a first structure and a second structure, the first structure includes a siloxane group, and the second structure includes a carboxyl group or an ester group. The first structure is more adjacent to the core than the second structure.
