▎ 摘　　要

NOVELTY - Preparation of graphene in-situ modified graphite carbon electrode material comprises expanding graphene in-situ modified graphite pyrolytically by using graphite oxide and talc at 10:1 mass ratio at 200-300 degrees C in sealed reactor. USE - Method for preparing graphene in-situ modified graphite carbon electrode material (claimed). ADVANTAGE - The method uses airtight reactor to reduce experimental costs and simplify process. The obtained electrode material enhances lithium storage capacity, cycle life and coulomb efficiency.
