Hybrid NiO-CoO nanocomposite for high energy supercapacitor applications

Energy storage research is focusing new cost effective and high specific capacitance electrode materials to meet the requirements of the energy demands. Herein, we studied hydrothermal derived hybrid NiO-CoO nanocomposite for supercapacitor applications. Electrochemical analysis of hybrid NiO-CoO nanocomposite of different reaction time was characterized and the obtained corresponding specific capacitance values were 168, 169 and 298 F/g respectively at 10 mV/s. Hybrid electrodes, suitable incorporation of CoO with NiO process increasingly enhanced electronic conductivity and electrochemical performance. 94.30% cyclic performance was maintained over 5000 cycles of charge discharge in galvanostatic charge discharge (GCD) profile.
