▎ 摘　　要

NOVELTY - Preparation of graphene-based electrocatalytic material involves dispersing graphene material in solvent, obtaining graphene dispersion, adding carbon material having particle diameter of 0.5-10 mu m, heating, such that the graphene material and carbon material are self-assembled to form gel-like mixture, removing the solvent in the resultant mixture and heat treating. The graphene material is graphene and/or graphene oxide. USE - Preparation of graphene-based electrocatalytic material used for lithium-ion battery electrode, supercapacitor electrode and lithium-air cell electrode (all claimed).
