Mixed transition metal oxides with hierarchical and porous structures are considered to be the promising electrodes for high-performance supercapacitors. Nickel-Tin-Oxide (NiSnO3 ) thin films are deposited by spray pyrolysis for electrochemical supercapacitors. These films are characterized by X-ray diffraction (XRD), scanning electron microscopy and UV–Vis spectrophotometer. XRD patterns confirm formation of Perovskite NiSnO3 . NiSnO3 thin films show flake and spongy type of morphology. The band gap energy is found to be in the range of 3.31–3.563 electrodes has been investigated through cyclic voltammetry, galvanostatic charge/discharge and electrochemical impedance spectroscopy (EIS) measurements in 23 electrode shows maximum specific capacitance of 3863 electrode attractive for high-performance supercapacitors.
