NOVELTY - Composite anode material comprises composite particles including vanadium matrix and non-metallic carbon material in mass ratio of 3-8:1. The precursor molecular formula of the vanadium matrix is VS4, which is a hexagonal snowflake flake structure. USE - The composite anode material is useful for lithium-sulfur battery (claimed). ADVANTAGE - The material is a multifunctional sulfur-fixing carrier, by combining standard physical and chemical adsorption and catalytic sulfur fixation, the sulfur fixation effect of lithium-sulfur batteries is improved, the sulfur fixation effect of lithium-sulfur batteries is enhance, inhibits the diffusion and dissolution of lithium polysulfide,, increases the capacity of the battery and improves the cycle life of the battery, and avoids the problem of poor sulfur fixation effect of lithium-sulfur batteries. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for: a method for preparing the composite anode material, comprising (i) adding vanadium source into ethylene glycol, adding sulfur source and non-metallic carbon material after fully dissolving, where the molar ratio of the vanadium source and the sulfur source is 1:1-11, and dissolving the mixture is fully and adding into the reactor and heating to 150-220 degrees C, after the reaction is completed, washing, centrifuging, filtering and drying in vacuum to obtain the VS4 composite material; (ii) adding the VS4 composite material into a tube furnace, introducing in inert gas and evacuating, heating to 200-500 degrees C at a rate of 1-10 degrees C/min for 1-5 hour, and heating at rate of 2-10 degrees C/min to 600-1000 degrees C for 0.5-3 hours for calcination to obtain V(x)Sy composite anode material; and (iii) combining the sulfur element and the V(x)Sy composite anode material.
