▎ 摘 要
NOVELTY - A graphene-based composite electrode material comprises polymer matrix and graphene component. The polymer matrix is composed of the graphene sheet structure of graphene derivative overlapping three-dimensional self-assembled porous structure having porosity of 10-95%. The polymer component is filled in the porous structure of the graphene substrate, for polymerizing the graphene substrate location. USE - Graphene-based composite electrode material (claimed). DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of graphene-based composite electrode material.
