Abstract

Electrochemical performance of MnSiO₃/MnO composite obtained as a byproduct of the plasma-assisted aluminothermic processing of Mn ore was investigated. The structural, morphological, elemental, and optical properties of the composite were analyzed. Cyclic voltammetry, galvanostatic charge–discharge, and electrochemical impedance tests were performed in a three-electrode configuration in two different electrolytes. The MnSiO₃/MnO electrode yielded high specific capacitance, decent cyclic stability, and good reversibility. A symmetric cell made with MnSiO₃/MnO// MnSiO₃/MnO delivered high energy and power densities in KOH electrolyte. In this study, an unused byproduct of the plasma-assisted aluminothermic processing of manganese ore was potentially repurposed in energy storage application.
