▎ 摘　　要

NOVELTY - The method involves uniformly coating graphene on a surface of copper belt. The surface of coated graphene foil is folded. The rolling process of graphene foil is carried out through plastic deformation, so as to obtain nano micro-structural organization of graphene. The cool rolling process of nano graphene copper foil is obtained according to the required specification. USE - Preparation method of nano-graphene copper foil used in cathode current collector area of lithium battery. ADVANTAGE - The production strength and electrical conductivity of nano-graphene copper foil are improved. DESCRIPTION OF DRAWING(S) - The drawing shows an explanatory view illustrating the preparation process of nano-graphene copper foil.
