description The structural characteristics of electrode materials play a crucial role in their potential applications. Therefore, designing the material’s structure rationally is one of the most effective methods to achieve high-performance electrodes. In this study, V−ZnCo<sub>2</sub>O<sub>4</sub> nanowires were synthesized on nickel foam using a simple hydrothermal method, and the prepared V−ZnCo<sub>2</sub>O<sub>4</sub>−2 electrode material exhibited a specific capacitance of 1621 C g<sup>−1</sup>. The potential applications of the prepared material were evaluated through device assembly, using V−ZnCo<sub>2</sub>O<sub>4</sub>−2 as the positive electrode and activated carbon as the negative electrode. The resulting device delivered an energy density of 127.5 Wh/kg, with a corresponding power density of 2700 W/kg. Additionally, the mechanical properties of the device were assessed, revealing that after multiple bends at different angles, the shape of the device remained well-preserved, further confirming its excellent mechanical stability.
