ABSTRACT = {This study highlights the superior electrochemical performance of Co<sub>3</sub>O<sub>4</sub>/Co<sub>3</sub>S<sub>4</sub> composite nanoparticles for supercapacitors, compared to individual Co<sub>3</sub>O<sub>4</sub> and Co<sub>3</sub>S<sub>4</sub>, synthesized using sol-gel, co-precipitation, and mechanical alloying methods. The composite combines pseudocapacitance and electric double-layer capacitance, as evidenced by cyclic voltammetry. It exhibits a specific capacitance of 722.9 F/g at 0.5 A/g and an energy density of 73.8 Wh/kg at 405 W/kg. Electrochemical impedance spectroscopy reveals low charge transfer resistance and excellent cycling stability is achieved, with 98.5% capacitance retention after 1500 cycles. These results confirm the composite's potential for high-performance energy storage applications.},
