Three‐Dimensional (3D) Bicontinuous Au/Amorphous‐Ge Thin Films as Fast and High‐Capacity Anodes for Lithium‐Ion Batteries

Three-dimensional (3D) Bicontinuous Au/amorphous-Ge thin-film anode for Li-ion batteries is prepared by thermal evaporation. The nanoporous Au acts as a volume buffer cushion. It also provides good electronic/ionic conductivities, enhancing the rate capability of the Au-Ge anode.
