Abstract
A hybrid supercapacitor consisting of Co-Mn oxide as a cathode, activated carbon as an anode, and 6 M KOH as a electrolyte was fabricated and its supercapacitor performance was investigated by means of cyclic voltammetry. The prepared supercapacitor showed the specific capacitance of 67.3 F/g, energy density of 18.3 Wh/kg, and power density of 237.7 kW/kg, respectively. It means that the supercapacitor can be used for the practical applications.
