The shell around the porous TiO2 not only acts as a buffer matrix against the volume expansion of silicon during repeated charging-discharging, but also enhances the dispersion of silicon particles. The amount of the basic catalyst NH4OH during the sol-gel reaction plays an important role in the formation of the TiO2 coating structure, which significantly affects its electrochemical characteristics.
