NOVELTY - Preparation of molybdenum trioxide/graphene lithium ion negative electrode material involves preparing ammonium molybdate solution and graphene slurry, adding the graphene slurry into reactor, adding the ammonium molybdate solution, stirring to obtain black solution, adjusting the pH value of black solution to 10.0, stirring to obtain milky white aqueous solution, adding the aqueous solution into high pressure reaction kettle, placing the kettle in oven, heating using hot water, keeping the reacting 110-130℃ for 3-5 hours, cooling to room temperature, washing with deionized water to obtain pH of the product to 7.0, washing with anhydrous ethanol for several times, washing all the product out of crucible, drying in vacuum oven to obtain precursor of molybdenum trioxide/graphene oxide composite material, placing the precursor in box-type muffle furnace for calcination under inert gas protection atmosphere to obtain gray product. USE - Preparation of molybdenum trioxide/graphene lithium ion negative electrode material used in lithium ion battery. ADVANTAGE - The method provides lithium ion negative electrode material improves the electrochemical performance of the molybdenum-based oxide as negative electrode material of lithium ion power battery, and can effectively improve the performance of the lithium ion battery.
