具有优异导电性和巨大储能能力的可拉伸纺织品（ST）是未来可穿戴电子服装的关键。本文中，源自两步无电沉积方法的可拉伸Ni@NiCoP涂覆的可拉伸织物呈现出完美的导电和电化学性能。它具有0.19 Ω sq（-1）的低方波电阻和532 S cm（-1）的高电导率。外层的NiCoP合金层可以有效地提高导电性和日常使用中的稳定性。此外，Ni和Co磷化物还具有较高的赝电容性能，其面积电容为877.6 mF cm（-2），重量电容为713 F g（-1）。然后将Ni@NiCoP ST构建成具有优异机械和电化学稳定性的可拉伸非对称超级电容器。最后，一个自供电系统被组装到实验服上，并在阳光照射下为电子手表提供持续电源，这表明Ni@NiCoP ST在未来可穿戴储能服装和电子产品中具有很大的潜力。
Stretchable textiles (STs) with both excellent conductivity and great energy storage capacity are crucial for future wearable electronic clothes. Herein, a stretchable Ni@NiCoP coated spandex textile derived from two step electroless deposition method presents perfect conductive and electrochemical performances. It delivers a low square resistance of 0.19 Omega sq(-1) and high conductivity of 532 S cm(-1). The outer NiCoP alloy layer can effectively enhance the conductivity and stability in daily utilization. Besides, the Ni and Co bimetallic phosphide contributes a high pseudocapacitive performance, with an areal capacitance of 877.6 mF cm(-2) and gravimetric capacitance of 713 F g(-1). The Ni@NiCoP ST is then constructed into a stretchable asymmetric supercapacitor with excellent mechanical and electrochemical stability. Finally, a self-powered system is assembled onto a lab coat and supplies continuous power for an electronic watch under sunlight illumination, demonstrating the Ni@NiCoP ST possesses promising potential in future wearable energy storage clothes and electronics.
