Abstract: Cathodic electrodeposited copper oxide thin films were prepared using 0.1 M aqueous (distilled water) copper sulphate solution onto the surface of stainless steel substrates. Deposited samples were characterized for structural and morphological analysis using XRD and SEM. Prepared samples were also analyzed using cyclic voltammetry, charge discharge and impedance spectroscopy. Electrode shows nearly rectangular capacitive behavior. The highest specific capacitance of 62 F/gm was calculated at scan rate 1 mV/sec in 1 M Na2SO4 electrolyte. The internal resistance observed from Nyquist plot which is about 1.95 Ω. Using ZsimpWin software matched equivalent circuit and circuitry parameters were reported.
