NOVELTY - Preparing vanadium-doped tungsten disulfide/graphene oxide composite electrode material comprises dispersing graphene oxide and sodium metavanadate in water uniformly to obtain solution A. The solution A is subjected to a hydrothermal homogeneous reaction, and after cooling, a product system A containing a graphene oxide matrix containing vanadium is obtained. Tungsten chloride and thioacetamide are uniformly dispersed in product system A to obtain suspension B. The suspension B is subjected to hydrothermal reaction to grow tungsten disulfide nanosheets, and the product system B is obtained after cooling, and after centrifugal washing the product system B, the powder is collected by freeze drying to obtain a vanadium-doped tungsten disulfide/graphene oxide composite material. The vanadium-doped tungsten disulfide/graphene oxide composite material is calcined and annealed to obtain a vanadium-doped tungsten disulfide/graphene oxide composite electrode material. USE - Method for preparing vanadium-doped tungsten disulfide/graphene oxide composite electrode material as a battery negative electrode material (claimed). ADVANTAGE - The method enables to prepare vanadium-doped tungsten disulfide/graphene oxide composite electrode material as a battery negative electrode material, which utilizes the larger specific surface area and better flexibility of graphene oxide to inhibit the agglomeration of WS2 nanosheets, and improves the electrochemical performance of the material and makes it have broad research value and application value in the electrochemical field.
