▎ 摘　　要

NOVELTY - Preparing graphene/silicon/conductive polymer composite anode material comprises e.g. (i) using concentrated sulfuric acid and potassium permanganate, taking graphite oxide into graphite oxide, then using graphite oxide ultrasonic peeling off into a graphene oxide material, and (ii) taking prepared graphene oxide and silicon powder, stirring to uniformity, adding initiator, initiating polymerization using polymer monomer polymerization and drying to obtain graphene oxide/silicon/conductive polymer film composite material, using hydrazine hydrate direct steam and carrying out reduction. USE - The method is useful for preparing graphene/silicon/conductive polymer composite anode material (claimed). ADVANTAGE - The method is suitable for the production of flexible electrode, no need to add any auxiliary agent and does not require the use of metal substrate. The foam material has good flexibility, exhibit good cycling stability and high specific capacity. DETAILED DESCRIPTION - Preparing graphene/silicon/conductive polymer composite anode material comprises (i) using concentrated sulfuric acid and potassium permanganate, taking graphite oxide into graphite oxide, then using graphite oxide ultrasonic peeling off into a graphene oxide material, and (ii) taking prepared graphene oxide and silicon powder, polymer monomer according to mixture ratio, stirring to uniformity, then adding initiator, under a suitable condition initiating polymerization, using polymer monomer polymerization, and further drying directly to obtain graphene oxide/silicon/conductive polymer film composite material, using hydrazine hydrate direct steam, using graphene oxide/silicon/conductive polymer film composite material, carrying out reduction to obtain graphene/silicon/electric conduction polymer foam material.
