Transition metal dichalcogenides (TMDs) emerge as promising electrode materials for next‐generation electrochemical energy‐storage devices. In the present study, vanadium disulfide (VS 2 ), an underexplored TMD, is investigated material supercapacitors. VS nanosheets are synthesized via a single‐step hydrothermal method at 220 °C 24 h. Multiple characterization techniques, including Fourier‐transform infrared, Raman spectroscopy, scanning electron microscope–energy dispersive X‐ray analysis, and transmission microscope, confirm formation of phase‐pure with hexagonal structure. The specific surface area, measured using Brunauer–Emmett–Teller 12 m g −1 . A capacitance 106 F current density 1 demonstrated symmetric supercapacitors fabricated these nanosheets. Using this device, energy 34 Wh kg power 800 W achieved. Moreover, supercapacitor maintains 94% retention after 9000 charge–discharge cycles 5 , highlighting potential efficient applications.

It is crucial for energy storage devices to construct electrode materials with excellent performance. However, enhancing density and cycling stability supercapacitors a significant challenge. We successfully synthesized CoNi2S4@Ni(OH)2 nanosheets on the surface of Ni foam substrate by two-step hydrothermal approach. The obtained products exhibit remarkable areal capacitance 1534 F g−1 at current 1 A g−1. Moreover, even after 10,000 cycles, specific remains 90% its initial value, highlighting exceptional long-term durability. Furthermore, an asymmetric supercapacitor (ASC) device incorporating material shows electrochemical delivers 58.5 mW h power 2700 W kg−1. outstanding performance mainly arises from selection materials, design structure, synergistic interaction between materials. result suggests that this holds great potential as material.
