ZnWO@NiCoO core-shell nanosheet array composites are synthesized on nickel foam a two-step hydrothermal method. The optimal conditions, including a Ni(NO)·6HO to Co(NO)·6HO molar ratio of 2 : 1, 12 hours reaction time, and 120 °C temperature, yield a specific capacitance of 875 C g at 1 A g. The electrode also maintains 81.1% capacitance after 10 000 cycles. The material's performance is attributed to its core-shell structure, which enhances ion diffusion and electron transport. This study presents a viable approach for high-performance supercapacitor electrodes.
