▎ 摘　　要

NOVELTY - Preparing graphene composite electrode material comprises (i) mixing graphite with metal salt or conductive polymeric monomer or mixture of metal salt and conductive polymeric monomer, adding auxiliary agent to solvent and performing ultrasonic reaction under power of 150-1000W for more than 1 hour, and (ii) washing and drying, where the prepared graphene composite electrode material is graphene/metal oxide composite electrode material, graphene/conductive polymer composite electrode material or graphene/conductive polymer/metal oxide composite electrode material. USE - The method is useful for preparing graphene composite electrode material. ADVANTAGE - The material has good specific capacitance, fast charge and discharge rate and good cyclic stability.
