In this paper, we have reported a low-cost electrochemical route for the formation of Ni-Si based alloys on Ni-substrates to be used as anode in lithium ion battery obtained through electrochemical reduction of silica powder (SiO₂). Electrodeposition of Ni-silicides has been carried out in a Al₂O₃- crucible placed inside a quartz electrochemical cell equiped with three-electrode system. Raman spectroscopy suggest formation of Ni-Silicides on the Ni-substrate. X-ray diffraction (XRD) pattern also supports formation of Ni-Si alloys on Ni-substrate.
