▎ 摘　　要

NOVELTY - The method involves carrying out first electrophoretic coating in the three-dimensional graphene colloidal solution with the metal substrate as the negative electrode, noble metal electrode and positive electrode. A three-dimensional graphene composite electrode material is obtained by performing second electrophoretic coating on the metal oxide colloidal solution with the metal substrate on which the three-dimensional graphene layer is deposited as the negative electrode, noble metal electrode and positive electrode. USE - Preparation method of three-dimensional graphene composite electrode material (claimed). ADVANTAGE - The excellent energy storage and cycle performance of three-dimensional graphene composite electrode material are achieved. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a three-dimensional graphene composite electrode material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view illustrating the preparation process of three-dimensional graphene composite electrode material.
