▎ 摘　　要

NOVELTY - Method for optimizing a lithium ion battery based on graphene/artificial graphite composite material mixing graphene oxide dispersion with artificial graphite powder dispersion and performing electrodeposition reduction, and extracting the graphene/artificial graphite composite material from mixed solution obtained by the reaction. The cathode of the lithium ion battery is made by electrodepositing graphite on the surface of artificial graphite particles. USE - The method is useful for optimizing lithium ion battery based on graphene-artificial graphite composite material. ADVANTAGE - The method has high first coulomb efficiency, and has higher specific capacity and better multiplying power performance.
