The invention discloses a method for cladding vanadium phosphate on lithium ion battery anode material lithium cobalt nickel manganate. The method comprises the following steps: (1) mixing vanadate, phosphate and reducing agent in the deionized water according to the vanadium element, the phosphorus element and the reducing element, regulating pH by using ammonia water, stirring to obtain a uniform solution, reacting for 20-48h at 160-240 DEG C; filtering, washing, drying to obtain the vanadium phosphate; (2) adding the lithium cobalt nickel manganate ternary anode material and the vanadium phosphate in a high-speed mixer, wherein the vanadium phosphate mass in the obtained mixture is 1%-10% of the total mass of the mixture; stirring under a condition of 500-2000rmp to obtain a uniform product; and (3) sintering at 200-400 DEG C in an non-oxidation atmosphere, and keeping temperature for 1-5h, cooling to obtain the vanadium phosphate clad lithium ion battery anode material lithium cobalt nickel manganate. By using method disclosed by the invention, the capacity and the cyclic performance of the lithium ion battery are effectively improved.
