Transition Metal Doped Trimanganese Tetraoxide Based Electrode Material for Supercapacitor Application

Abstract

Many studies are being conducted in the field of energy storage devices to improve the newlineperformance of an electrode materials for future application. In recent years, numerous research newlinehave been published that fully define Nano level synthesis techniques, dopants and composite newlinebased work for improving the charge storing capability and long cycle life of energy storage newlinedevices, particularly in supercapacitor. In this current era, researchers prefer eco-friendly synthesis newlinetechniques to rectify unnecessary hazardous issues. Since, environmental friendly technique along newlinewith good cyclic stability was one of the major focuses in scientific society. This doctoral work newlinehas been carried out in the motivation to attain high specific capacitance to improve cyclic newlinestability. Transition metal oxides (TMO) of nanostructure explored excellent potential applications newlinein energy storage devices. Here, the spinel Mn3O4 prepared by various method and investigations newlinewere carried out to examine their compatibility for supercapacitor. Since pure Mn3O4 and newlinetransition metal oxide (Co, Fe and Ni) doped Mn3O4 nanomaterials have been synthesized by newlinehydrothermal method and are compared in terms of physical and electrochemical characteristics. newlineThe XRD analysis corresponds to the body centered tetragonal spinel structure with space group newlineas l41/amd (141). Using a High resolution Transmission Electron Microscope newline(HRTEM) and a newlineHigh resolution Scanning Electron Microscope (HRSEM), the surface morphology of the newlinesynthesized samples was examined newline
