Electrochemical methods were developed for the deposition of nanosilicon onto a 3D virus‐structured nickel current collector. This nickel current collector is composed of self‐assembled nanowire‐like rods of genetically modified tobacco mosaic virus (TMV1cys), chemically coated in nickel to create a complex high surface area conductive substrate. The electrochemically deposited 3D silicon anodes demonstrate outstanding rate performance, cycling stability, and rate capability. Electrodeposition thus provides a unique means of fabricating silicon anode materials on complex substrates at low cost.
