Thus it would be a very desirable material for high capacity batteries. The large volume expansion encountered upon Li incorporation into Si will fracture bulk Si but not Si nano¬wires. In their Rapid Research Letter on p. 4, H. Föll et al. address the fabrication of Si nanowire arrays with optimized geometry via electrochemical pore etching in Si followed by isotropic chemical etching until the pore walls coalesce and nanowire arrays remain. Galvanically deposited Cu provides the electrical connection and protects the remaining bulk Si. First test batteries made with such Si nanowires anodes not only demostrated the expected high capacity but also showed virtually no capacity losses for more than 60 charge/discharge cycles.
