The silicon-based composite material that can be used as a secondary battery negative electrode material is disclosed. The first step of the silicon-based composite material, silicon chloride to a mixture of alcohol and 2 ryuin glycol to form a porous material; A second step of forming a silicon oxide by heat treating the porous material in an inert gas atmosphere which is content (x) of oxygen is represented as 0 <x <2 is within the range of the general formula SiOx; A third step of forming a composite powder of Si-SiOx by the silicon oxide and metallic silicon formed in the second step and the solid phase reaction mixture; A fourth step of forming a composite material of Si-SiOx-C by mixing and reacting a solid carbonaceous material to the SiOx-Si compound powder is formed in the third step; And a fifth step of heat treatment in a temperature range of less than the Si-C-SiOx a composite of more than the reduction temperature of the carbon in an inert gas atmosphere and the alloying reaction temperature of silicon and carbon; can be prepared via the.
