This work describes a promising strategy for large-scale fabrication of silicon (Si) nanotubes. The process began with preparation of silica nanotubes using rod-like NiN2H4 as a template and the resulting silica nanotubes were then converted to Si nanotubes by a thermal reduction process assisted with magnesium powder. The electrochemical properties of Si nanotubes were investigated as anode of lithium-ion batteries. It was demonstrated that the as-developed Si nanotubes showed significantly improved rate capability and long-term cycling performance compared with commercial silicon meshes. (c) 2013 Elsevier B.V.
