A novel SiOxCy film is successfully fabricated by electrodeposition on a carbon paper substrate with vinyl trichlorosilane as the precursor in air. It has been found that the SiOxCy film is evenly and uniformly distributed on the carbon paper. The long-term cycling stability of the SiOxCy film anode is tested at a rate of 1 C for 1000 cycles, showing that the charge capacity decreases from 1919.8 mA h g-1 to 1020.5 mA h g-1 over 1000 cycles, suggesting good long-term cycling stability. The good cycling stability of the SiO xCy film anode is attributed to the ordered structure of the SiOxCy film. Moreover, the interwall space could provide a buffer for Si expansion during the Li insertion/extraction process, thus improving the cycle life of Si anodes.
