▎ 摘　　要

NOVELTY - Preparation of lithium battery electrode material based on graphene modification involves (s1) ultrasonically dispersing spherical graphite and graphene oxide in solvent, and heating until the solvent is volatilized to obtain solid mixture, (s2) carbonizing obtained mixture to obtain graphene-modified material, and (s3) mixing obtained material with nano conductive agent, binder and dispersant. USE - Preparation of lithium battery electrode material based on graphene modification. ADVANTAGE - The method uses evaporating and volatilizing to prepare modified graphene material, and the electrode material prepared by mixing with the nano conductive agent exhibits high coulombic efficiency and stability.
