▎ 摘　　要

NOVELTY - Preparing superfine metal oxide/two-dimensional graphene cathode composite material involves refluxing reduced graphene oxide and metal acetate to glycol, reacting for 1-2 hours, filtering, washing and drying to obtain superfine metal oxide/two-dimensional graphene cathode composite material. The mass concentration of reduced oxidation graphene is 0.3 grams/liter, metal acetate is 5-20 millimoles/liter, where metal acetate is metal nickel acetate or cobalt acetate. USE - Method for preparing superfine metal oxide/two-dimensional graphene cathode composite material for preparing energy storage material (claimed). ADVANTAGE - The method enables to prepare superfine metal oxide/two-dimensional graphene cathode composite material which has unique properties, short electronic transmission path, improved the material conductivity and lithium storage performance and realized the effectively store energy for providing good material. It has great application prospect.
