<p>In this study, we successfully synthesized a novel flower-like composite V₂O₅@CoV-LDH, which was directly anchored onto nickel foam through a two-step hydrothermal method to enhance surface area and stability. The synthesized flower-like composite V₂O₅@CoV-LDH features V₂O₅ as the first layer and CoV-LDH as the second layer, effectively merging the high capacitance and energy density of V₂O₅ with the large surface area and multivalent states of CoV-LDH. Moreover, this unique bilayer composite structure, directly anchored onto nickel foam, significantly enhances the overall stability of the electrode material. This design demonstrates outstanding performancedue to a strong synergistic effect, which provides the composite with more reactive sites, shorter ion transport pathways, and enhanced cycling stability. The test results show that the V₂O₅@CoV-LDH electrode achieves a high specific capacitance of 1822 F g⁻¹ at 1 A g⁻¹ and retains 85.99% of its capacitance after 5000 charge–discharge cycles, demonstrating excellent stability. The asymmetric supercapacitor assembled with the V₂O₅@CoV-LDH electrode and activated carbon electrode delivers an energy density of 59.85 Wh kg⁻¹ at a power density of 900 W kg⁻¹. After 10,000 cycles at 5 A g⁻¹, the specific capacitance remains at 88%, indicating promising potential for practical applications.</p>
