NOVELTY - Preparation of silicone cathode material composition comprises pressing silicon dioxide to form block shape; heating blocky silicon dioxide by external device; condensing heated silicon dioxide; crushing obtained silica product to obtain precursor; and coating carbon to precursor, and carrying out graphene coating modification. USE - The method is used for preparing silicone cathode material composition. ADVANTAGE - The method uses graphene to coat silicon. The graphene toughness is better. It can inhibit volume expansion. The cost is low.
