NOVELTY - Preparing intercalation coating composite modified anode material comprises (i) dissolving vanadium pentoxide powder in water with purity not less than deionized water, then adding metal ion salt solution and conductive carbon material, and mixing uniformly to obtain the reaction solution; (ii) transferring the reaction solution to the reaction vessel, reacting for 12-48 hours at 140-200℃, collecting the solid product and cleaning, and drying to obtain the intercalation composite modified anode material, and the mol ratio of vanadium pentoxide to the metal ion in the metal ion salt solution is 1:2-15 and the mass ratio of vanadium pentoxide to conductive carbon material is 1:1-4. USE - The intercalation coating composite modified anode material is used as active material in the anode system zinc ion battery (claimed). ADVANTAGE - The method: introduces the metal ion to vanadium pentoxide layer and covers conductive carbon material, which can make it have large interlayer distance and good structure stability; utilizes in the active substance to the anode zinc ion battery, which improves the capacity and cycle life of the battery. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for use of intercalation coated composite modified anode material, is prepared by the above method.
