▎ 摘　　要

NOVELTY - Method for modifying graphite involves fully dissolving the asphalt in an organic solvent, adding graphite and high-conductivity graphene to the obtained solution, mixing them uniformly to coat the graphene surface, removing the organic solvent and carbonizing the solid product to make the asphalt carbide coated on the outer surface of the graphene to obtain a modified graphite. USE - The modified graphite is useful as cathode material in lithium-ion battery (claimed). ADVANTAGE - The modified graphite has excellent multiplying power performance, quick charging performance, safety performance and cycle performance. The method is simple to operate, easy to mass production, and provides graphite with high conductivity. The cathode material has rich storage lithium, increasing the lithium storage site and transmission channel. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a modified graphite.
