NOVELTY - Preparation of silicon-graphene composite anode material, involves dispersing graphene powder in solvent to obtain graphene aqueous dispersion, adding silicon powder to graphene aqueous dispersion, dispersing to obtain mixture (I), transferring mixture (I) to hydrothermal reactor, reacting, drying obtained material, crushing, grinding, sieving to obtain mixture (II), dissolving asphalt in organic solvent, mixing with mixture (II) and graphite flake, dispersing evenly, placing obtained product in porcelain combustion boat, calcining, crushing, grinding and sieving. USE - Preparation of silicon-graphene composite anode material. ADVANTAGE - The method enables preparation of silicon-graphene composite anode material with high capacity. The preparation method is simple and economical.
