Abstract: Highlights: Sequential hydrothermal-electrodeposition integration for hierarchical NiCo2O4/NiCoS architecture construction. High areal capacitance of 6.94 F cm−2 at 2 mA cm−2 with 98.85% Coulombic efficiency. NiCoS growth regulation via electrodeposition time control for performance optimization. Effective oxide–sulfide contact facilitates interfacial charge transfer and structural stability. The NiCo2O4/nickel cobalt sulfide (NiCoS) electrode was constructed on a nickel foam (NF) substrate using a combination of hydrothermal synthesis and constant potential electrodeposition. The NiCo2O4 prepared via an in situ hydrothermal method followed by calcination served as an intermediate layer, providing structural support and abundant active sites for the subsequent electrodeposition of the NiCoS top layer. The NiCoS loading amount was optimized by adjusting the deposition time. The optimized NiCo2O4/NiCoS electrode delivered an areal specific capacitance (Cs) of 6.94 F cm−2 at a discharge current density of 2 mA cm−2 with a coulombic efficiency of 98.85%. It retained 64.52% of its initial capacitance as the current density increased from 2 to 80 mA cm−2 and exhibited an equivalent series resistance (RESR) of 1.06 Ω cm−2. Furthermore, the NiCo2O4/NiCoS electrode retained 88.24% of its initial capacitance after 700 charge/discharge cycles, eventually stabilizing at 81.25% within 4000 cycles. [ABSTRACT FROM AUTHOR]
