Hierarchical NiCo₂O₄@CuS composite electrode with enhanced surface area for high-performance hybrid supercapacitors.

ABSTRACT: Hierarchical binder-free NiCo₂O₄@CuS composite electrodes have been successfully fabricated on a nickel foam surface using a facile hydrothermal method and directly used as a battery-type electrode material for supercapacitor applications. The surface morphological studies reveal that the composite electrode exhibited porous NiCo₂O₄ nanograss-like structures with CuS nanostructures. The surface area of the composite is significantly enhanced (91.38 m² g^-1) compared to NiCo₂O₄ (52.16 m² g^-1), with a predominant pore size of 3-6 nm. This synergistic combination enhanced the electrode's electrochemical properties. The NiCo₂O₄@CuS electrode delivered an impressive
