Inspired by our results that the electrochemical activity and electrical conductivity of ZnO nanowires were greatly improved after hydrogenation , we designed and fabricated hydrogenated single - crystal ZnO @ amorphous ZnO - doped MnO2 core - shell nanocables ( HZM ) on carbon cloth as SC electrodes , showing excellent performance such as areal capacitance of 138 . 7 mF / cm ( 2 ) and specific capacitance of 1260 . 9 F / g .
