▎ 摘　　要

NOVELTY - A graphene-based composite anode material has graphene porous structure, and 10-50 %mass cathode material particles uniformly distributed between surface layer and sheet. USE - Graphene-based composite anode material is used for lithium ion battery, supercapacitor and sodium ion battery (all claimed). ADVANTAGE - The graphene-based composite anode material is manufactured by simple method with high productivity. The battery formed of the graphene-based composite anode material has excellent charging/discharging efficiency.
