Abstract

See full text

A silicon/carbon composite or a silicon alloy/carbon composite is formed with a homogeneous silicon-containing thin film or silicon-containing alloy thin film on the surface of a conductive carbon material, where the composite may be used for a large-capacity electrical storage device when used as a negative electrode material for forming an electrical storage device negative electrode, and exhibits excellent charge-discharge cycle characteristics. A carbon-containing thin film is formed on a surface of a conductive carbon material by chemical vapor deposition (CVD) that utilizes a carbon-containing gas and a silicon-containing thin film or a silicon-containing alloy thin film is formed on the conductive carbon material by chemical vapor deposition (CVD) that utilizes a silicon-containing gas alone, or utilizes a silicon-containing gas and a carbon-containing gas.
