Abstract
Abstract Here, we report the fabrication of one step NiO nanopyramid thin film as a binder-free electrode with improved electrochemical properties using a reactive magnetron sputtering. The crystalline nature, surface morphology and chemical composition of the as deposited NiO thin films were analyzed by X-ray diffraction (XRD), Raman spectroscopy, Field emission scanning electron microscopy (FE-SEM), Atomic force microscopy (AFM) and X-ray Photoluminescence spectroscopy (XPS). The electrochemical measurements were carried out using cyclic voltammetry, electrochemical impedance spectroscopy (EIS) and galvanostatic charge
