Microscale supercapapcitors based on hierarchical nanoporous hybrid electrodes consisting of 3D bicontinuous nanoporous gold and pseudocapacitive manganese oxide deliver an excellent stack capacitance of 99.1 F cm−3 and a high energy density of 12.7 mW h cm−3 with a retained high power density of 46.6 W cm−3.
