Recently silicon (Si)-based materials with highest-known theoretical charge capacity of 4200 mAh/g have been considered as promising anode materials in lithium-ion battery (LiB). Specially, nanostructured Si have drawn particular attention as it can effectively suppress volume expansion due to free space surrounding the nanostructures, and thus improve life cycle of the LiB. In this paper, we have reported a low-cost electrochemical route for the formation of nanostructured Si-layer on graphite-substrates obtained through electrochemical reduction of silica powder (SiO2).
