Abstract Transition metal oxide nanocomposites featuring diverse structures have garnered significant attention in the realm of supercapacitors. This interest is attributed to their cost‐effectiveness, high surface area, rapid transport ions and electrons, ability deliver specific capacitance. In this work, sea‐urchin shaped NiCo 2 O 4 reduced graphene (NCO/rGO) were synthesized via facile hydrothermal route. NCO/rGO nanocomposite was subsequently loaded on nickel foam (NF) using drop casting method build electrodes. The structural morphological characteristics our designed electrodes such as NCO investigated by scanning electron microscope (SEM), energy dispersive spectroscopy (EDX), X‐ray diffraction (XRD), Fourier infrared transform (FTIR) while cyclic voltammetry (CV), galvanostatic charge‐discharge (GCD), electrochemical impedance (EIS) techniques performed address efficacy which reveal redox‐mediated charge storage NCO‐rGO. As‐prepared electrode exhibited capacitance 875 F g −1 at current density 1 A demonstrates potential a suitable candidate supercapacitor applications.
