Fabrication of high-performance symmetric supercapacitor using hybrid cobalt spinel ferrite-decorated MoS2 nanosheets

Year: 2025

Type: article

Abstract: This study presents a facile hydrothermal-ultrasonication synthesis of MoS₂@CoFe₂O₄ hybrid nanocomposites (NPs) for constructing symmetric supercapacitor electrodes. The electrodes were fabricated with 5, 10, and 20 wt% of the hybrid nanocomposite as the active material, and their electrochemical properties were evaluated in both aqueous and a gel electrolyte system with H₂SO₄ (0.5 M) . The supercapacitor device incorporating 10 wt% of the composite material and tested with the gel electrolyte demonstrated excellent electrochemical performance, achieving a specific capacitance ( Cs ) of 528.60 F g⁻¹ at 10 mV s⁻¹ . Additionally, the cell exhibited exceptional stability over 10,000 cycles, with a Coulombic efficiency of 98.9 % and a high energy density of 66.94 Wh kg⁻¹ at 500 W kg⁻¹ . The superior performance of the proposed supercapacitor can be attributed to the synergistic effects of the MoS₂@CoFe₂O₄ nanocomposite and gel electrolyte, which collectively enhanced charge storage capacity and durability. Given its outstanding cyclic stability, energy density, and specific capacitance, this system holds great promise for advanced energy storage applications .
