As an important member of the transition-metal chalcogenides (TMCs) family, VS₄ has numerous intriguing chemical and physical properties that benefit from its peculiar crystallographic structure. Nowadays, how to achieve the high energy density and long cycle life in supercapacitors remains an open challenge. To address this issue, we propose a bio-inspired nanomaterial structure of anemone-like VS₄ that consists of nanorods with a diameter of approximately 30–100 nm and a length of 1–2 μm are synthesized by a facile solvothermal method. The electrochemical performance of anemone-like VS₄ as a supercapacitor electrode is systematically tested in three-electrode and two-electrode systems. In the three-electrode configuration, the anemone-like VS₄ is exhibiting a remarkably high specific capacitance of 617 F g⁻¹ at a current density of 0.4 A g⁻¹. The fabricated symmetric supercapacitor (two-electrode system) has achieved an excellent energy density (113.6 W h kg⁻¹ at a power density of 720 W kg⁻¹). In addition, the device is showing excellent cycling stability, with 93.8% capacity retention over 12,000 galvanostatic charge-discharge cycles at a current density of 6 A g⁻¹. The results suggest that the anemone-like VS₄ has the potential to be used as a high-performance supercapacitor electrode material.

作为过渡金属硫属化物（TMC）家族的重要成员，VS ₄具有许多有趣的化学和物理特性，这些特性得益于其独特的晶体结构。如今，如何在超级电容器中实现高能量密度和长循环寿命仍然是一个开放的挑战。为了解决这个问题，我们提出了一种仿生的海葵状VS ₄纳米材料生物启发结构，该结构由直径为30–100 nm且长度为1–2μm的纳米棒组成，采用简便的溶剂热法合成。在三电极和两电极系统中系统地测试了类似海葵的VS ₄作为超级电容器电极的电化学性能。在三电极配置中，类似海葵的VS ₄ 在0.4A g ^-1的电流密度下，Pb呈现出非常高的617 F g ^-1的比电容。所制造的超级电容器对称（双电极系统）已经实现了优异的能量密度（113.6 W时千克^-1 在720的功率密度钨千克^-1）。另外，该装置显示出优异的循环稳定性，在6 A g ^-1的电流密度下，在12,000个恒电流充放电循环中具有93.8％的容量保持率。结果表明，类似海葵的VS ₄具有用作高性能超级电容器电极材料的潜力。
