Abstract
Using a silicon-containing carbon-based composite material represented by the compositional formula: SiOxCyHz. In this formula, “x” is from 0.8 to 1.7, “y” is from 1.4 to 7.5, and “z” is from 0.3 to 1.3. The composite material is preferably obtained by: obtaining a cured product by crosslinking (A) a crosslinkable group-containing organic compound, and (B) a silicon-containing compound capable of crosslinking the crosslinkable group-containing organic compound, and heat treating the obtained cured product. The composite material of the present invention has high reversible capacity and stable charge and discharge cycle characteristics, and has high initial charge and discharge efficiency. Therefore, the composite material of the present invention is suitable for an electrode of an electricity storage device, particularly of a lithium or lithium-ion secondary battery.
