▎ 摘　　要

NOVELTY - Preparing graphene-conductive polymer composite material comprises (1) spary drying graphene oxide solution or modified graphene solution to obtain graphene microsphere, (2) mixing and immersing the graphene microsphere with liquid conductive polymer monomer to obtain reaction precursor, (3) mixing the reaction precursor with acid solution containing oxidizing agent, carrying out polymerization reaction of the mixture to obtain intermediate product, and (4) reducing the intermediate product. USE - The method is useful for preparing graphene-conductive polymer composite material (claimed). ADVANTAGE - The method avoids graphene in large current charging and discharging thus improving multiplying power performance of large current charging and discharging. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a graphene-conducting polymer composite material, comprising graphene microsphere and conductive polymer, where the conductive polymer is covered on a surface of the graphene microsphere.
