▎ 摘　　要

NOVELTY - Preparation of graphene supercapacitor electrode material involves depositing 0.02-0.5 g/L graphene material on surface a nanoporous gold film by electrochemical cyclic voltammetry at 0-2 V, number of cycles of 50-600, and scanning speed of 10-200 mV/second. USE - Preparation of graphene supercapacitor electrode material (claimed). ADVANTAGE - The method enables preparation of graphene supercapacitor electrode material having excellent stability, power density, dimensional stability and cycle characteristics, and specific capacity of 864 F/g or less. The electrode material maintains 90% specific capacity, even after 2000 cycles.
