Supercapacitors (SCs) have received widespread attention as excellent energy storage devices, and the design of multicomponent electrode materials construction ingenious structures are keys to enhancing performance SCs. In this paper, MoS2 nanorods were used carrier structure induce anchoring CoAl-LDH nanosheets grow on surface nickel foam (NF) in situ, thus obtaining a uniformly distributed nanorod@CoAl-LDH nanosheet core–shell nanoarray material (MoS2@CoAl-LDH/NF). On one hand, nanorod-structured core provides high conductivity support, accelerates electron transfer, avoids agglomeration nanosheets. other arrays abundant interfacially active sites, which accelerate electrolyte penetration enhance electrochemical activity. The synergistic effect two components unique nanostructure give MoS2@CoAl-LDH/NF capacity (14,888.8 mF cm–2 at 2 mA cm–2) long-term cycling (104.4% retention after 5000 charge/discharge cycles). integrated MoS2@CoAl-LDH/NF//AC device boasts voltage range spanning from 0 1.5 V, achieving peak density 0.19 mW h cm–2. Impressively, it maintains capacitance rate 84.6% enduring 10,000 cycles, demonstrating exceptional durability stability.

Abstract Transition metal sulfur oxides have emerged as promising candidates for advanced energy storage due to their multi‐electron redox activity and tunable nanostructures. Among them, Co‐Ni‐O‐S composites are particularly attractive supercapacitors owing high density. However, conventional synthesis methods often require prolonged processing times (>10 h) or high‐temperature treatments (>80 °C), which limit practical applications. This work addresses these challenges by developing amorphous‐nanocrystalline intertwined nanohybrid nanosheet arrays through a rapid alternating current (AC) electrodeposition method (1 under ambient conditions. The unique architecture combines the advantages of amorphous phases (enhanced ion diffusion pathways) nanocrystalline domains (efficient charge transport), leading exceptional specific capacitance 4804 F g⁻¹ (or 959 mAh g −1 , 2402 C ) at 1 A g⁻¹, 82.2% retention after 5000 cycles (5 g⁻¹), near 100% Coulombic efficiency (CE). assembled asymmetric supercapacitor achieves an density 199.4 Wh kg⁻¹ 754 W kg⁻¹, bridging performance gap between batteries capacitors.
