NOVELTY - An anode material preparing method involves dispersing graphene oxide in deionized water, adding hydrochloric acid and mixing to obtain a solution-A, and dissolving stannous chloride in the solution-A by mixing to obtain solution-B, which is reacted and washed to obtain graphene-stannic oxide composite material, which is dispersed in deionized water to form solution-C, followed by dissolving water-soluble polymeric substance in the solution-C to obtain solution-D. The solution-D is transferred into a reaction vessel to obtain reacted product, which is cooled, washed, dried and sintered. USE - Method for preparing an anode material of lithium ion battery. ADVANTAGE - The method enables preparing the anode material with increased lithium storage capacity, better effect of permeating electrolyte, increased electric conductivity and increased performance. DETAILED DESCRIPTION - An anode material preparing method involves dispersing graphene oxide in deionized water, adding hydrochloric acid and uniformly mixing to obtain a solution-A, and dissolving stannous chloride in the solution-A by mixing to obtain solution-B. The solution-B is reacted at 40-80 degrees C for 4-12 hours and washed to obtain graphene-stannic oxide composite material. The obtained composite material is dispersed in deionized water to form solution-C, followed by dissolving water-soluble polymeric substance in the solution-C by mixing to obtain solution-D. The solution-D is transferred into a reaction vessel. The reaction vessel is placed in an environment at 160-200 degrees C for 2-12 hours to obtain reacted product. The reacted product is cooled, washed, dried in 10-1000 ppm protective atmosphere containing oxygen and inert gas, and sintered at 700-800 degrees C to obtain finished product.
