Nickel cobalt oxide (NiCo2O4) thin films were grown via a chemical spray method on a conducting glass substrate. The crystalline structure, morphology and electrochemical studies were reported. The X-diffraction pattern result showed the NiCo2O4 films were polycrystalline spinel structure. The development of two dimensional growths of nanocrystalline surface morphology of NiCo2O4 thin films is observed by FE-SEM. The supercapacitor performance of the thin films was recorded between scan rates of 5 to 200 mV s-1 and obtained maximum supercapacitance of 777 F/g at scan rate 5 mV/s, which demonstrated that the nanocrstalline NiCo2O4 thin film was a excellent electrode material for energy storage application.
