▎ 摘　　要

NOVELTY - Preparation of graphene material, involves dispersing graphene oxide containing amino group in an electrolytic salt, heating to melt the electrolytic salt and form a graphene oxide dispersion, and electrolyzing using two aluminum rods as negative and positive electrodes, and the graphene oxide dispersion as electrolyte to form a graphene-aluminum composite coating on the surface of negative electrode. USE - Preparation of graphene material. ADVANTAGE - The graphene oxide layer is deposited on the negative electrode to obtain graphene-aluminum composite material with uniform aluminum distribution, and excellent conductivity and mechanical strength.
