A hierarchical furball-like WO₃ electrode material, based on stainless-steel mesh, was successfully synthesized via a simple in situ hydrothermal method. The electrode materials obtained are made from a self-assembled nanorod core and a connected/quasi-connected nano-thorn network shell, and could help utilize all the surface or near-surface regions for faradaic reaction. Furthermore, the furball-like WO₃ special microstructure provides a more effective charge storage area, exhibiting a high specific capacitance of 8.35 F cm⁻² and excellent cycling stability (93.4% of its initial value after 10 000 cycles). These performances indicate this furball-like WO₃ material would be a promising candidate for high performance supercapacitors.

用于高性能超级电容器电极的三维分级毛球状三氧化钨微球的合成

通过简单的原位水热法成功合成了一种基于不锈钢网的分级毛球状WO ₃电极材料。获得的电极材料由自组装的纳米棒核和连接/准连接的纳米刺网络壳制成，可以帮助利用所有表面或近表面区域进行法拉第反应。此外，毛球状WO ₃特殊微结构提供了更有效的电荷存储区域，表现出8.35 F cm ^-2的高比电容和优异的循环稳定性（10 000 次循环后其初始值的93.4%）。这些表现表明这种毛球状的WO ₃材料将成为高性能超级电容器的有希望的候选者。
