A novel SiOC composite anode material for a Li battery was realized by electrochemical co-deposition of Si, C. and O elements. The composite was deposited by reduction of SiCl(4) in a propylene carbonate based solution. After the initiation process by reduction of the composite in a Li(+) containing electrolyte solution, the SiOC composite was found to be about 3.3 mu m in average thickness and the composite performed as a Li battery anode with over 1000 mAh g(-1) of Si for more than 2000 cycles, and moreover have continued for 7000 cycles with gradual degradation.
