▎ 摘　　要

NOVELTY - Anode active material comprises a carbon material (210), and a silicon structure (220) attached to the carbon material, where the silicon structure includes a silicon nanoparticle, a metal thin film formed on a surface of the silicon nanoparticle, and graphene coated on a surface of the metal thin film. USE - Anode active material. ADVANTAGE - The anode active material is capable of improving the performance and lifetime of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for manufacturing an anode active material, which involves: a. forming a metal thin film on a surface of a silicon structure including a silicon nanoparticle by immersing the silicon structure in a metal plating solution; b. coating graphene on the metal thin film in a preset environment; and c. mixing the graphene-coated silicon structure with a carbon material. DESCRIPTION OF DRAWING(S) - The drawing shows a perspexctive view of an anode active material. 210Carbon material 220Silicon structure
