Herein, we have developed a two-step hydrothermal reaction to fabricate core−shell nanostructured ZnCo 2 O 4 @NiMn-LDH on nickel foam. The electrode material composition is optimized by different feed ratios of Ni in the shell structure, which is composed of NiMn-LDH. In three-electrode electrochemical analysis, ZnCo 2 O 4 @NiMn-LDH (2:1) exhibited a specific capacitance of 5165 F/g at a current density of 1 A/g in 6 M KOH electrolyte. Moreover, the rate capability of retention of ZnCo 2 O 4 @NiMn-LDH (2:1) reached 80% at a current density of 4 A/g. Finally, a solid-state asymmetric supercapacitor is assembled by using ZnCo 2 O 4 @NiMn-LDH as the positive electrode and α-Fe 2 O 3 as the negative electrode placed inside the Swagelok cell device with a separator. The fabricated supercapacitor ZnCo 2 O 4 @ NiMn-LDH (2:1)||α-Fe 2 O 3 exhibits an energy density of 64.6 Wh/kg at a power density of 748 W/kg and a cyclic stability of 97.9% after 3000 cycles. For the zinc−air battery (ZAB) application, ZnCo 2 O 4 @NiMn-LDH (2:1) delivered a lower overpotential of 390 mV at a 50 mA/cm 2 current density with good stability in an alkaline medium. It exhibited a power density of 43 mW/cm 2 with stability throughout the 200 h. Both applications suggest that ZnCo 2 O 4 @NiMn-LDH is considered an efficient nanostructured electrode for energy applications.

Curing agents for epoxy resin (EP) are one of the most important branches in the polymer materials field due to their enormous potential in many fields, but constructing them in a well‐controlled curing temperature remains challenging. Herein, a novel curing agent is constructed by the zirconium metal‐organic framework (UiO‐66) and [P4442]2[IDA] through an impregnation method. [P4442]2[IDA]@UiO‐66 is utilized as a functional nanofiller and curing agent to construct the [P4442]2[IDA]@UiO‐66/EP nanocomposites. The chemical structures of [P4442]2[IDA]@UiO‐66 were investigated by XRD, SEM, DSC, and TG characterizations. The various [P4442]2[IDA]@UiO‐66 with different loading amounts of [P4442]2[IDA] were used to investigate the curing behaviors of the EP‐51. The DSC results confirm that the curing temperature of the [P4442]2[IDA]@UiO‐66/EP is higher than that of [P4442]2[IDA]/EP. In addition, the kinetic parameters and the activation energy of the curing reaction were acquired according to the fitting of Kissinger equation and Ozawa equation. The drying time of [P4442]2[IDA]@UiO‐66/EP system at 40 °C was enhanced 17 times compare to that of [P4442]2[IDA]/EP system. This study opens new avenues for the rational design of EP nanocomposites by employing ionic liquids@MOFs composite materials as curing agent for wide engineering applications.

Bismuth oxide (Bi 2 O 3 ) materials are considered as great promising anodes for aqueous batteries on account of the high capacity as well as wide potential plateau. Nevertheless, the low conductivity and severe volumetric change of Bi 2 O 3 in the course of cycling are the main limiting factors for their application in energy-storage systems. Herein, we propose and design unique hierarchical heterostructures constructed by Bi 2 O 3 and Bi 2 S 3 nanosheets (NSs) manufactured immediately on the surface of carbon nanotube fibers (CNTFs). The Bi 2 O 3 −Bi 2 S 3 (BO-BS) exhibits enhanced conductivity and increased stability in comparison with pure Bi 2 O 3 and Bi 2 S 3 . The BO-BS NSs/CNTF electrode indicates exceptional rate capability and cycling stability, while creating a high reversible capacity of 0.68 mAh cm −2 at 4 mA cm −2 , as anticipated. Additionally, the quasi-solid-state fibrous aqueous Ni//Bi battery that was built with the BO-BS NSs/CNTF anode delivers an exceptional cycling stability of 52.7% capacity retention after 4000 cycles at 80 mA cm −2 , an ultrahigh capacity of 0.35 mAh cm −2 at 4 mA cm −2 , and a high energy density of 340.1 mWh cm −3 at 880 mW cm −3 . This work demonstrates the potential of constructing hierarchical heterostructures of bismuth-based materials for high-performance aqueous Ni//Bi batteries and other energy-storage devices.
