- The present study shows the electrodeposition of MnO2 from KMnO2 solution and its electrochemical studies. XRD analysis shows the electrodeposited MnO2 has nano-sized particle of 18 nm. The electrochemical properties have been investigated using the cyclic voltammetry, galvanostatic charge/discharge and impedance techniques. The electrodeposited MnO2 shows good electrochemical behavior with high specific capacitance value of ca. 306 F g-1. Moreover, it shows high capacitance stability of 90% over 1000 charge/discharge cycles. Impedance result shows low solution resistance and charge transfer resistance, an indication of the conductive nature for the electrodeposited film.
