Abstract

A manganese oxide (MnO2) electrode has been developed by using potentiostatic electrodeposition method and characterized for its compositional, morphological and afterward envisaged in pseudocapacitor applications. The elemental analysis of MnO2 electrode was studied using X-ray photoelectron spectroscopy (XPS). The supercapacitive properties of MnO2 electrode studied using cyclic voltammetry and galvanostatic charge-discharge measurements in 1M Na2SO4 electrolyte. A high specific capacitance of 626 Fg−1 was obtained within the potential range of −0.3 to 0.8 V in 1M Na2SO4 electrolyte. Additionally, MnO2 electrode exhibited high charge/discharge efficiency of 98.32%. The present study signifies successful application of potentiostatic electrodeposited MnO2 thin films as a supercapacitor electrode.
