Abstract

We first report the successful synthesis of porous germanium with ordered hierarchical structures, via controlled etching, and show its performance as an anode in a new metal–air battery. Our experimental results demonstrate the potential use of porous germanium in a high power density Ge–air energy conversion cell, showing a stable long-term discharge profile at various current drains.
