NOVELTY - A lithium ion battery anode material preparing method involves adding 5-8 mass% graphene powder, 5-8 mass% graphene dispersant and 84-90 mass% solvent to a stirring tank and stirring uniformly to obtain a composite slurry, applying the mixed composite slurry to the surface of the 12-16 mu m foil and coating thickness of 2-3 mu m, followed by compacting the coated foil by a roller press to 12-18 mu m, after the compaction is completed, baking the foil in a vacuum oven at 40-50 degrees C for 12-15 hours to obtain the finished product. USE - Method for preparing lithium ion battery anode material. ADVANTAGE - The method enables preparing lithium ion battery anode material with high conductivity and reduced impedance, in cost effective manner.
