Today, the increasing demand for energy in the world has led to a focus on efficient and low cost energy storage devices. Many essential energy sources take a significant number of forms, including atomic energy and conventional sources, such as petroleum, coal and natural gas. Recently, super-capacitors have attracted research due to their high power densities, quick charge-discharge and long life cycles. The objective of this thesis is to alter the morphological structure of nickel oxide (NiO) utilizing different surfactants and furthermore to analyze the impact of these surfactants on the electrochemical properties of the nickel oxide. The unlimited applications of nickel oxide relate to lower cost, commercial availability and high electrochemical properties. The nickel oxide was synthesized by a hydro thermal method. For the amalgamation of nickel oxide for changing morphologies, nickel (II) nitrate hexahydrate, urea CO(NH2)2, ammonium fluoride (NH4F), cetyltrimethylammonium bromide (CTAB), poly (vinyl pyrrolidone) (PVP), sodium dodecyl sulfate (SDS) were used for the synthesis nickel oxide. The obtained precursor was calcined at 500 °C to prepare phase pure nickel oxide. The crystal size determined using XRD for NiO-SDS was observed to be 27.5 nm. The electrochemical properties of the nickel oxide were studied using cyclic voltammetry and galvanostatic charge –discharge measurements. The highest specific capacitance of 315 F/g was observed in 3 M LiOH for NiO-SDS sample at scan rate of 5 mV/s.
