| description | With the increasing societal demand for sustainable and renewable energy, supercapacitors have become research hotspots. Transition metal oxides, due to their high capacitance and abundant resources, are the preferred electrode materials. However, their poor conductivity and volume changes limit performance enhancement. Therefore, the development of heterogeneous structure electrode materials has become an important research direction. In this study, Zn-CoS@Ni(OH)<sub>2</sub>-1 nanosheets were synthesized on a nickel foam substrate via a three-step hydrothermal synthesis method, exhibiting excellent capacitance performance. In terms of capacitance, the material achieved a specific capacitance of 624 F/g at a current density of 1 A/g. When assembled into an asymmetric supercapacitor with Active Carbon materials, the device demonstrated an energy density of 35.4 Wh kg<sup>−1</sup>. |
