The present invention discloses a SiC-based battery anode material made by secondary granulation and a preparation method thereof. The SiC substrate battery anode material made by secondary granulation contains carbon base material, a plurality of nano silicons, and a modification layer. The preparation method for SiC-based battery anode material made by secondary granulation includes embedding the nano silicons into the surface pores on carbon base material and the encapsulation of modification layer, so as to improve the uniformity during battery slurry conditioning and seepage of anode material and further achieve the effects of effectively enhancing the cycling performance and stability of batteries.
