  • Amorphous MnO$_2$$.$ nH$_2$O in 1M KOH aqueous electrolyte proves to be an excellent electrode for a faradic electrochemical capacitor cycled between -0.5 and +1.0 versus Ag/AgCl. In order to observe morphology and crystalline structure of MnO$_2$powder, we analyzed it by XRD and SEM. The effect of oxidation treatment on MnO$_2$electrode was observed by different oxidation voltages. A maximum capacitance of 364F/g was obtained by 1.1V oxidation treatment. This capacitance was attributed solely to a surface redox mechanism
