CuMn2O4 electrode materials with a unique hexagonal morphology for supercapacitor applications were synthesized via the co-precipitation technique along with dual hydroxide treatment. Various characterization techniques, such as powder X-ray diffraction (PXRD), Fourier-transform infrared spectroscopy (FTIR), Ultraviolet-Visible Spectroscopy (UV-vis), Scanning Electron Microscopy (SEM), and Energy-dispersive X-ray analysis (EDS), were employed to assess the synthesized material. The electrochemical performance of the CuMn2O4 electroactive material was evaluated using a three-electrode technique for supercapacitor applications. The hexagonal morphology of the synthesized material provides ample free space and promotes superior electrochemical performance. Cyclic voltammetry (CV) analysis confirmed the pseudocapacitive behaviour, and the maximum specific capacitance was measured at 507.6 F g-1 at a scan rate of 5 mV s-1 Electrochemical impedance spectroscopy was used to determine the solution resistance (Rs) and charge transfer resistance (Rct). Overall, the findings suggest that the synthesized CuMn2O4 electrode material holds great potential for use in high-performance supercapacitor applications.
