NOVELTY - Preparation of reduction-oxidation graphene modified nickel-cobalt-manganese ternary anode material comprises dispersing nickel-cobalt-manganese ternary anode material in solvent to obtain raw material dispersion liquid, dropping ammonia water solution to make the pH alkaline, adding surface modifier, stirring, filtering, and drying to obtain surface modified nickel-cobalt-manganese ternary anode material; dispersing the surface-modified nickel-cobalt-manganese ternary anode material in a small amount of solvent to obtain dispersion liquid, dropping graphene oxide (GO) solution, stirring, filtering, and drying to obtain graphene oxide coated nickel-cobalt-manganese ternary anode material; and subjecting the graphene oxide coated nickel-cobalt-manganese ternary anode material to heat treatment reduction to obtain reduced graphene oxide (rGO) coated nickel-cobalt-manganese ternary anode material. USE - The method is for preparation of reduced graphene oxide-modified nickel-cobalt-manganese ternary anode material. ADVANTAGE - The reduced graphene oxide obtained by the heat treatment reduction has high electron conductivity and stable chemical property, contains a large amount of defects, can make Li+ ion pass through the plane of graphene, and provides high capacity and good circularity. The design of the coating structure enables to obtain anode material with high capacity and excellent cycle performance.
