Hollow nanostructures of metal oxides as next generation electrode materials for supercapacitors

Abstract Hollow nanostructures of copper oxides help to stabilize appreciably higher electrochemical characteristics than their solid counter parts of various morphologies. The specific capacitance values, calculated using cyclic voltammetry (CV) and charge-discharge (CD) studies, are found to be mu...
