Abstract

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 SiCl4 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 μm 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.
