Symmetric supercapacitors (SSCs) with remarkable energy storing capability, high specific power as well as long‐term cyclic stability were fabricated from nickel tungstate (NiWO₄) @ nickel oxide (NiO_x) decorated commercial cotton fabrics (CCFs). A commercial cotton‐based textile was first made conductive by the state of the art ultrasonic spray coating method. This was followed by chemical and electrochemical processes to decorate activated CCFs with NiO_x and NiWO₄, respectively. The assembled SSCs had the merit of high specific energy of 12 μWh cm⁻² at a specific power of 69 μW cm⁻² while showing reasonable cyclic stability. Fabricated devices retained over 80% of their initial capacitance after 5500 continuous charge/discharge cycles. The flexibility of the devices was investigated under bending, twisting, and folding providing reliable evidence on the wearability of the fabricated SSCs. Cyclic voltammograms of the fabricated NiWO₄@NiO_x@CCF SSCs showed only a slight change and retained over 95% of the capacitance under bending and folding. The fabricated NiWO₄@NiO_x@CCF SSCs, in this regard, are promising energy storage systems to power up high‐performance wearable electronics.

基于钨酸镍装饰的可穿戴超级电容器装饰的商用棉织物

由钨酸镍（NiWO ₄）@氧化镍（NiO _x）装饰的商品棉织物（CCFs ）制成了具有出色储能能力，高比功率以及长期循环稳定性的对称超级电容器（SSC ）。首先，通过先进的超声波喷涂方法使商品棉织物具有导电性。接下来是化学和电化学过程，分别用NiO _x和NiWO ₄装饰活化的CCF 。组装的SSC得到12μWh厘米的高比能量的优点^-2在69的特定功率μW厘米^-2同时表现出合理的循环稳定性。在5500个连续的充电/放电循环后，预制设备保留了其初始电容的80％以上。在弯曲，扭曲和折叠下研究了设备的灵活性，为制造的SSC的耐磨性提供了可靠的证据。制成的NiWO ₄ @NiO _x @CCF SSC的循环伏安图仅显示很小的变化，并且在弯曲和折叠下保留了超过95％的电容。在这方面，制造的NiWO ₄ @NiO _x @CCF SSC是有前途的储能系统，可为高性能可穿戴电子设备供电。
