摘要

Researchers have conducted an in-depth analysis to meet the demands of energy through green, sustainable solutions. In this regard, rare-earth metal nanocomposites have been incorporated due to their remarkable electrochemical performance. In this research, a facile hydrothermal method was employed to synthesize Sm2O3/Co2Mn3O8 nanocomposite for supercapacitor application. The prepared nanocomposites were confirmed by various characterization techniques such as scanning electron microscopy (SEM), X-ray diffraction spectroscopy (XRD), Fourier-transform infrared spectroscopy (FTIR), and energy-dispersive spectroscopy (EDX). The SEM analysis demonstrated nanosphere-like morphology, and EDX confirmed the peaks of Sm, Mn, Co, and O. The electrochemical performance was assessed via cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). The prepared Sm2O3/Co2Mn3O8 nanocomposite exhibited superior specific capacitance and energy density values of about 1947.61 F/g at 5 mV/s and 33.10 Wh/kg, respectively. The outcome recommends Sm2O3/Co2Mn3O8, an efficient electrode material in the era of energy storage systems.
