Abstract:
We have developed a novel technique providing fabrication of nanoporous silicon films on nonsilicon substrates. Magnetron sputtering of an Al+Si composite target with subsequent selective etching off the aluminum from the deposited film were used to produce nanoporous silicon films on stainless steel substrates. These films were found to have a highly nanoporous skeleton formed by connected 20-200 nm silicon grains. They demonstrated an efficient Li accumulation/release during charging/discharging cycles combined with a high mechanical durability.
