silicon oxide-carbon composite, method for producing the same, and energy storage device having the same

And providing a carbon composite, and a method of manufacturing the energy store containing them - silicon oxide. A silicon oxide - in the carbon composite method, provides a reaction solution containing an organic solvent including an aromatic compound. It generates a plasma in the reaction solution to form a crystalline carbon structure. It is dispersed in the reaction mixture the crystalline carbon structure makes the slurry by the addition of the silicon halide and the polyhydric alcohol (polyol). The heat treatment to remove the organic solvent from the slurry.
