Abstract

Aqueous zinc-ion batteries (ZIBs) have garnered remarkable attention owing to high safety, low price, environmental friendliness, and versatile adaptability. In this paper, we present the fabrication of a fiber-based ZIB using a slurry composed of ZnVOH and carbon black as the cathode material. This battery demonstrates high capacity and a robust bonding interface. Notably, the binding strength and uniformity of the slurry on the fiber surface play a pivotal role in energy-storage capabilities. Carbon black serves the dual purpose of providing a conductive medium and a viscosity adherence to the fiber surface. ZIBs containing 15 % carbon black exhibit a high capacity of 319.8 mAh g⁻¹ at a current density of 0.5 A g⁻¹. In addition, the fully solid-state fiber battery demonstrates superior electrochemical performance under various bending deformations coupled with optimized electrical conductivity. Importantly, its seamless integration with textiles underscores its potential for large-scale industrial production of flexible fiber-shaped ZIBs, providing a compelling solution for flexible energy storage.

高性能柔性锌离子电池：碳纤维上的浆料涂层

水性锌离子电池（ZIB）因其安全性高、价格低廉、环保和多功能适应性而备受关注。在本文中，我们使用由 ZnVOH 和炭黑组成的浆料作为阴极材料，制作了一种基于纤维的 ZIB。这种电池具有高容量和坚固的结合界面。值得注意的是，纤维表面浆料的结合强度和均匀性对储能能力起着关键作用。炭黑具有双重作用，既能提供导电介质，又能粘附在纤维表面。在电流密度为 0.5 A g-1 时，含 15% 炭黑的 ZIB 显示出 319.8 mAh g-1 的高容量。此外，这种全固态纤维电池在各种弯曲变形条件下均表现出卓越的电化学性能，同时还具有优化的导电性。重要的是，该电池与纺织品的无缝集成凸显了其在柔性纤维状 ZIB 大规模工业化生产方面的潜力，为柔性储能提供了一个极具吸引力的解决方案。
