An investigation on the electrochemical performance of Mn₃O₄-based aqueous symmetric supercapacitor devices.

ABSTRACT: Manganese (ii, iii) oxide (Mn₃O₄) is one of the promising materials in the realm of high-performance supercapacitors. The high theoretical specific capacitance, low cost, non-toxicity, environmental compatibility, and natural abundance made it significant in the research field. A low-temperature hydrothermal synthesis method was adopted to prepare Mn₃O₄ (hausmannite) nanoparticles with a tetragonal spinel structure. The as-prepared nanoparticles were assessed for the structural, elemental, electrical, optical and nitrogen adsorption-desorption studies through XRD, FTIR, Raman spectroscopy, XPS, DC conductivity, UV-vis absorption and BET analyses. Morphological studies were done using FESEM and TEM and a mixture of nanorods and nanocubes were obse
