摘要: 水系锌碘电池面临多碘化物的穿梭、活性物质溶解以及传统刚性电极的机械柔韧性差等问题，导致容量快速衰减限制了在可穿戴设备中的应用。本文通过静电纺丝技术构建了柔性自支撑纳米复合材料(Fe-ZIF8@CNF)，该设计结合了纳米反应器的限域和催化优势，以及自支撑框架的机械耐久性和优化的离子/电子传输特性，有效降低了集流体界面阻抗。使Fe-ZIF8@CNF电极展现出优异的循环稳定性能(软包电池10 C下实现600次循环)和出色的比容量(在5 C下提供193.94 mAh∙g−1)。这项工作为开发高性能柔性水系储能电极提供了可拓展的新路径。
Abstract: Aqueous zinc-iodine batteries suffer from severe issues including polyiodide shuttle effect, active material dissolution, and poor mechanical flexibility of conventional rigid electrodes, which lead to rapid capacity decay and greatly restrict their practical applications in wearable devices. In this work, a flexible self-supported nanocomposite (Fe-ZIF8@CNF) was fabricated via electrospinning technology. This design integrates the confinement and electrocatalytic advantages of nanoreactors with the mechanical durability and optimized ion/electron transport properties of the self-supported framework, thereby effectively reducing the interfacial impedance of the current collector. Consequently, the Fe-ZIF8@CNF electrode delivers outstanding cycling stability (600 cycles at 10 C in soft-pack batteries) and superior specific capacity (193.94 mAh∙g−1 at 5 C). This work offers a scalable and innovative strategy for the development of high-performance flexible electrodes toward aqueous energy storage systems.
