▎ 摘　　要

NOVELTY - A nickel-graphene composite material, is obtained by fixing a material to the graphene sheets nickel substrate as a carrier, followed by depositing metallic nickel on the graphene surface. USE - Nickel-graphene composite material for use in super nickel hydrogen battery. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: (1) a method for preparing nickel-graphene composite material, which involves fixing expanded graphite sheet on one side of nickel metal and another side as anode electrified with electrolyte solution to obtain nickel-graphene substrate, drying and washing the substrate material, followed by processing through ion plating or sputtering process to obtain finished product (2) a method for preparing nickel-graphite carbon electrode.
