A highly redox-active ternary nickel sulfide and cobalt-anchored carbon nanocomposite (NiS-Co@C) electrochemical electrode is synthesized by a two-step pyrolysis-hydrothermal method using biomass-derived carbon. The high-crystalline hierarchical porous nanostructure provides abundant voids cavities, along with large specific surface area, to improve the interfacial properties. as-synthesized achieved capacity of 640 C g−1 at 1 g−1, retention 93% over 5000 cycles, revealing outstanding Nickel nanoparticles embedded in framework improved redox activity, ion transport, conductivity, resulting dominant diffusion-controlled battery-type behavior. Moreover, hybrid supercapattery, based on NiS-Co@C as positrode capacitive-type activated negatrode, maximum energy/power 33 Wh kg−1/7.1 kW kg−1 91% after cycles. synergistic effect combinatorial battery–capacitor behavior supercapattery has energy–power considerably, leading development next-generation energy storage technologies.
