A one‐step fabrication method is used to make hierarchically structured reduced graphene oxide (rGO) at relatively low temperatures via a mechano‐chemical reduction mechanism. The prepared rGO has a high surface area and can deliver a high specific capacitance even at high operation rates. This mechano‐chemical mechanism is a unique way to simultaneously tailor the chemical and physical structure of the graphene material and thus mass‐produce a unique rGO suitable for energy‐storage applications.
