▎ 摘　　要

NOVELTY - Method for preparing graphene material, involves scraping paste comprising reduced graphene oxide and conductive carbon black in a mass ratio of 1:1, uniformly mixing with binder comprising tetrafluoroethylene copolymer, placing on disc-shaped stainless steel support, drying at ambient temperature, and performing deposition of conductive layer of polypyrrole resulting from electropolymerization using cyclic voltammetry to obtain graphene material. USE - The graphene material is used for supercapacitor. ADVANTAGE - The graphene material ensures specific capacity of 55-65 mF/cm2.
