Scientists at the Fraunhofer FEP institute have developed a non-toxic and efficient manufacturing process for porous silicon layers for use as lithium-ion battery anodes.

The vacuum coating process for the syntheses of porous silicon thin film deposits silicon and zinc simultaneously on metal substrates. The breakthrough was discovered during project PoSiBat— an investigation into whether highly porous silicon layers had the potential to boost the energy density of lithium-ion batteries.
