NOVELTY - A surface modifier is added to deionized water and stirred, to obtain solution (s1). Molybdenum disulfide powder and graphite powder are added to solution (s1), and dispersed, to obtain molybdenum disulfide powder dispersion and graphite powder dispersion. Molybdenum disulfide powder dispersion and graphite powder dispersion are subjected to jet cavitation and centrifugal separation, and upper solution is taken. The upper solution is vacuum filtered and dried, to obtain gray powder. The gray powder is calcined, to obtain molybdenum disulfide nanosheet/graphene composite material. USE - Preparation of molybdenum disulfide nanosheet/graphene anode material used for lithium-ion battery. ADVANTAGE - The method enables preparation of molybdenum disulfide nanosheet/graphene anode material having high conductivity, dispersion stability and stacking characteristics of molybdenum disulfide nanosheets by simple and environmentally-friendly method. The lithium-ion battery comprising the molybdenum disulfide nanosheet/graphene anode material has excellent workability. DETAILED DESCRIPTION - A surface modifier is added to deionized water at predetermined ratio and vigorously stirred for predetermined time, such that the surface modifier is fully soluble in water, to obtain solution (s1) for preparing molybdenum disulfide nanosheets and graphene. Molybdenum disulfide powder and graphite powder are separately added to solution (s1) in predetermined ratio, and evenly dispersed, to obtain molybdenum disulfide powder dispersion and graphite powder dispersion. Molybdenum disulfide powder dispersion and graphite powder dispersion are subjected to jet cavitation for predetermined time, charged to centrifuge tube and centrifugally separated. The centrifuged solution is maintained still for predetermined time, and the upper solution is taken. The upper solution is vacuum filtered and dried under vacuum, to obtain gray powder. The gray powder is placed in quartz boat, and tube furnace is filled with argon, and the gas flow rate is controlled and calcined at predetermined temperature for predetermined time, to obtain molybdenum disulfide nanosheet/graphene composite material.
