N2 - Metal sulfide nanomaterials are addressed as electrode for supercapacitor applications, but their utilization is constrained due to less stability and poor capacity performance. The doping strategy is a successful method for enhancing the capacitance nature, cyclic stability, and conductivity property. In this investigation, nickel-doped copper sulfide (Ni–CuS) with different concentrations was synthesized by using the facile hydrothermal approach to resolve energy storage issues. A number of approaches are used to evaluate the structure, purity, phases, material composition, textural aspects, and morphology. In comparison to other electrode materials, the Ni0.007CuS electrode contains a substantial specific capacitance (Cs) value of 1485.355 F g−1 with an impressive energy density (Ed) of 94.27 Wh Kg−1 as well as power density (Pd) of 338 W Kg−1. The stability analysis of Ni0.007CuS exhibited 92.96% capacitance retention after 5000th GCD cycles with only minor structural degradation, as investigated with X-ray diffraction (XRD). The achieved finding from the electrochemical impedance spectroscopy (EIS) suggested that the Ni0.007CuS exhibits the 1.68 Ω charge transfer resistance (Rct). The two-electrode results show that Ni0.007CuS contains a Cs of 620 F g−1 and an Ed of 128 Wh kg−1. Our research demonstrates that including of nickel dopant in the form of Ni0.007CuS nanoarray enhances the efficiency of charge migration by facilitating a convenient route for the transfer of electrolyte ions. As a result, we conclude that these cathode materials are suitable for use in supercapacitor applications.
