N2 - The development of advanced hybrid nanostructures is essential for improving the electrochemical performance of next-generation energy storage devices. In this study, we report the fabrication of a hierarchically organized Co-MOF@WS2 composite grown on nickel foam, designed for high-performance supercapacitor applications. The present study presents a hierarchically organized Co-MOF@WS2 supported on nickel foam as an electrode material with exceptional performance for supercapacitors. This study demonstrates that the Co-MOF@WS2 material achieves an exceptionally high specific capacitance of 2901 C/g at 2 A/g in a 1 M KOH solution, surpassing the capacitances of previously documented MOF-based materials. Co-MOF@WS2 is employed as the positive electrode and activated carbon (AC) serves as the negative electrode, an asymmetric supercapacitor (ASC) device attains a high energy density of 80.1 Wh/kg at a power density of 1008 W/kg, with a capacitance retention of 83.6% after 12,000 cycles.
