▎ 摘　　要

NOVELTY - A graphene-nanomaterial composite comprises a graphene stacked structure including graphene films stacked on one another; and a nanomaterial between the graphene films and bonded to at least one of the graphene films by a chemical bond. USE - The graphene-nanomaterial composite is useful for producing electrode, and electric device selected from a supercapacitor, a secondary battery, a fuel cell, and a solar cell (all claimed). ADVANTAGE - The graphene-nanomaterial composite is capable of increasing an electrode capacity per volume by stacking graphene sheets. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) an electrode, comprising a current collector; and the graphene-nanomaterial composite on the current collector; and (2) an electric device, comprising the electrode.
