description The invention discloses a graphene-based silicon-carbon compound negative material and a preparation method thereof. The method comprises the following steps: stirring a liquid acrylonitrile oligomer liquor to form a microcyclized liquid acrylonitrile oligomer liquor; dispersing silicon powder in a solvent, stirring and adding a titanate coupler for ultrasonic dispersion to obtain a silicon powder dispersion liquid; mixing the liquors; adding graphite, uniformly mixing and meanwhile, evaporating the solvent to obtain a mixture of silicon, graphite and acrylonitrile oligomer; preoxidizing the mixture and grinding to obtain precursor powder; and under protection of an inert gas, calcining the precursor powder to obtain the graphene-based silicon-carbon compound negative electrode material. The preparation method provided by the invention is simple and controllable in preparation process and low in preparation cost, and the graphene-based silicon-carbon compound negative material prepared not only has high condu
