We report a novel RuO₂-NPG//Co(OH)₂-NPG asymmetric supercapacitor with a high specific capacitance and a wide potential window in which bifunctional nanoporous gold is used as both the highly conductive supports of the pseudocapacitive oxides and the 3D current collectors in the device. The RuO₂-NPG and Co(OH)₂-NPG electrodes can reach specific capacitances of 1300 F g^-1 and 1800 F g^-1, respectively, which provide comparatively high specific capacitances in relation to metal oxide/carbon electrodes, giving rise to an asymmetric oxide pseudocapacitor with a large capacitance of ∼350 F g^-1, high working voltage of 1.6 V and an ultrahigh energy density of ∼120 W h kg ^-1.
