N2 - In this work, MgNiO2 material is prepared by a facile sol-gel method as an electrode material for supercapacitor application. The prepared MgNiO2 material is characterized by X-ray diffraction (XRD), thermogravimetric analysis (TGA), Fourier transform infrared spectroscopy (FT-IR), and elemental analysis (EDS). The electronics conductivity is 1.9 × 10-4 S cm-1. The electrochemical performance of the prepared MgNiO2 material was examined in an aqueous electrolyte of 1 M KOH. The electrochemical reaction of the prepared MgNiO2 material shows the EDLC behaviour from the shapes of the CV curves. The prepared MgNiO2 nanomaterial revealed good electrochemical performance with a maximum specific capacitance of 78 F/g at a rate of current density of 0.1 A/g. The above result delivered a simple, low cost and high-performance approach for a supercapacitor application.
