A type of single‐crystal gallium nitride mesoporous membrane is fabricated and its supercapacitor properties are demonstrated for the first time. The supercapacitors exhibit high‐rate capability, stable cycling life at high rates, and ultrahigh power density. This study may expand the range of crystals as high‐performance electrode materials in the field of energy storage.
