Vanadium carbide-MXene (V2CTx) is considered a rising star among 2D materials and an ideal electrode material for energy storage due to its unique features. However, oxidation layer restacking can impair specific capacity (Cs) cycling performance. Considering this challenge, we have developed composite consisting of amorphous nickel boride (NixB NPs) V2CTx. To prevent the layers improve performance supercapacitor, NixB was decorated between gaps surface. The V2CTx composites were prepared by simple etching direct liquid-phase methods. Under optimized conditions, NixB/V2CTx modified foam exhibited improved Cs value 705.9 C g−1 rate capability 53.8 % at current density 10 A g−1; excellent stability 120.5 after 10,000 cycles in 3 M KOH. values, shortened ion diffusion paths, swift electron transfer, are surface entrapped/gaps filled NPs. For practical application, asymmetric device with reduced graphene oxide (rGO) as positive negative electrodes fabricated.

β-MnO2, as the most stable phase of polycrystalline MnO2, has a narrow tunnel structure that limits ion diffusion and electron transfer, restricting its application in supercapacitors. In this work, we present novel all-in-one MnO2-based material, β-MnO2@δ-MnO2, featuring unique three-dimensional architecture with ultrathin δ-MnO2 nanostructures vertically grown on β-MnO2 network. This innovative design leverages structural support to enhance electrode material's specific surface area effectively mitigate volume changes during adsorption/desorption, key factor for improving cycling stability. As result, β-MnO2@δ-MnO2 composite demonstrates exceptional electrochemical performance, remarkable stability 98% capacitance retention after 10,000 cycles. Additionally, it maintains 74.2% when current density increases from 1.0 20 A g–1, showcasing an outstanding rate capability. When assembled into asymmetric supercapacitor device, electrodes deliver high 287.3 mF cm–2 significant energy 159.3 μWh cm–2. work represents advancement optimization applications, demonstrating practical benefits rational nanostructure design. The not only enhances performance storage devices but also holds potential other offering new opportunities development flexible, high-performance systems.
