In this work, pure carbon spheres (CSs) and Mn3O4 nanoparticles (NPs) embedded on carbon sphere were synthesized by hydrothermal method. The prepared CS/Mn3O4 was examined with structural, functional, and morphological properties by XRD, FTIR, and SEM analysis. The average grain size and crystalline size of Mn3O4 coated carbon sphere were found through morphological analysis. The element ratio, composition and distribution of the prepared Mn3O4 coated carbon sphere were analyzed through EDS and Mapping analysis. Electrochemical performance such as redox behavior, charge storage/discharge capacity and resistive nature of Mn3O4 /CSs was evaluated using cyclic voltammetry, chronopotentiometry, and electrochemical impedance spectroscopic analysis.
