In this study, a Ba/Co-based composite electrode was successfully synthesised via the hydrothermal method and evaluated for its potential use in supercapacitor applications. The structural and chemical characteristics of the prepared electrode were examined through X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) analyses, confirming the formation of well-defined crystalline phases and the effective incorporation of both barium and cobalt oxides. The electrochemical performance of the Ba/Co electrode revealed a specific capacitance of 143 F/g at a current density of 1 A/g, demonstrating excellent energy storage capability. Moreover, the electrode exhibited remarkable cyclic stability, retaining 94.37% of its initial capacitance after 5000 charge–discharge cycles, indicating superior structural integrity and durability. These results can be attributed to the synergistic effects between the metal oxide components, which provide high electrical conductivity and enhanced redox activity. The outstanding performance highlights the potential of Ba/Co composite electrodes as efficient, stable, and cost-effective candidates for next-generation energy storage devices. Overall, the findings suggest that further optimisation of the material composition and microstructural design could lead to even higher energy and power densities, paving the way for practical applications in advanced supercapacitor technologies.
