▎ 摘　　要

NOVELTY - The method involves mixing nickel salt, cobalt salt and manganese salt in certain stoichiometric ratio into de-ionized water by stirring to obtain uniform mixed solution. Two neural water solutions are uniformly dropped into a reactor sealing at 100-200 degrees centigrade in an oven. The mixture is uniformly dispersed in oxidized graphite alkene aqueous solution with concentration of 0.1-10 mg/ml. Oxidized graphene is added into a graphene-rich lithium oxide powder surface and filtered, washed and dried to obtain a lithium ion battery. USE - Method for preparing a lithium-rich anode material of a lithium ion battery. ADVANTAGE - The method enables improving multiplying power performance and circulation stability of a lithium-rich material, preparing the lithium-rich material without protection of inert gases in reaction process, simplifying reaction and saving cost, and ensures high electrochemical activity, better product rate performance, cycle stability and repeatability. The method enables reducing different batches material prepared by physical and chemical performance fluctuation. DESCRIPTION OF DRAWING(S) - The drawing shows a photographic representation of a method for preparing a lithium-rich anode material of a lithium ion battery.
