Abstract
The increasing demand for energy in the world led to focus on more efficient energy storage devices. Energy can be stored in various kind of devices such as batteries, capacitors and fuel cells. Among them, supercapacitors are very attractive due to their high power densities, fast charge-discharge behavior and long life cycles. They can be used in hybrid cars and devices where high-power delivery is required. The objective of this work is to study the effect of morphology of nickel oxide on their electrochemical properties. The morphology of nickel oxide was modified using various surfactants. Structural characterization performed using scanning electron microscopy reveals the nanostructure of nickel oxides. The electrochemical properties of nickel oxide were studied using cyclic voltammetry and galvanostatic charge discharge measurements. A very high specific capacitance of about 315 F/g was observed at 5 mV/s in alkaline electrolyte. It was observed that charge storage capacity depends on morphology of nickel oxide.
