| description | This study reveals, for the first time, the excellent capability of MnWO4-CNT as a supercapacitor electrode compared to MnWO4. In previous research conducted on this compound, RGO was used to enhance its electrochemical properties. The objective of this study is to investigate the effects of CNT on the electrochemical properties of the compound, which also yielded promising results. The physical and morphological analysis of MnWO4 and MnWO4-CNT was conducted using Raman, XRD, BET, and SEM-EDX techniques. The electrochemical performance of the samples was assessed through cyclic voltammetry (CV), impedance electrochemical spectroscopy (EIS), and galvanostatic charge–discharge (GCD). Notably, MnWO4-CNT exhibited a significant specific capacitance of 1849.14 F·g−1 at a scan rate of 10 mV·s−1. The stability evaluation of the samples demonstrated a high capacitance retention of 81.2% and 89.4% for MnWO4 and MnWO4-CNT, respectively. The substantial specific capacity, along with the favorable stability of MnWO4-CNT, positions it as a highly promising material for utilization in supercapacitor electrodes. |
