Abstract

Porous manganese oxide film for electrochemical supercapacitors is electrodeposited directly onto a nickel sheet by cathodic electrodeposition in a KMnO4 aqueous solution. The obtained film is characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), cyclic voltammetry (CV) and galvanostatic charge/discharge test. The SEM images showed the formation of porous structure on the surface of nickel substrate. The CV curves are tested in a Na2SO4 aqueous solution, showing double layer capacitive behavior in the potential window of -0.2 ~ 1.0 V versus SCE. The highest specific capacitance is 165.7 F g-1 with a scan rate of 1 mV s-1.
