Many studies are being conducted in the field of energy storage devices to improve the performance of an electrode material for future application. In recent years, numerous research have been published that fully define Nano level synthesis techniques, dopants and composite-based work for improving the charge storing capability and long cycle life of energy storage devices, particularly in supercapacitor. In this current era, researchers prefer eco-friendly synthesis techniques to rectify unnecessary hazardous issues. Since, environmental friendly technique along with good cyclic stability was one of the major focuses in scientific society. This work has been carried out in the motivation to attain high specific capacitance to improve cyclic stability. Here, the spinel Mn₃O₄ prepared by various method and investigations were carried out to examine their compatibility for supercapacitor. The XRD analysis corresponds to the body centered tetragonal spinel structure with space group as l4₁/amd (141). Using a High resolution Transmission Electron Microscope (HRTEM) and a High resolution Scanning Electron Microscope (HRSEM), the surface morphology of the synthesized samples was examined. The size of the nanoparticles was calculated using Image-J software. The Electrochemical execution of Mn₃O₄ was analysed through cyclic voltammetry (CV), Chronopotentiometry (CP), cyclic stability and Electrochemical Impedance Spectroscopy (EIS).
