摘要

随着可穿戴电子行业的不断创新，柔性锌离子电池（FZIBs）因其低成本和高安全性的优势，在可穿戴电子产品和便携式设备的研究中备受关注。在这项工作中，我们开发了一种基于皮革的新型凝胶电解质（LGE），具有高离子传导性、良好的柔韧性和高稳定性，用于柔性锌离子电池。在室温下，该电解质的离子电导率为1.36×10-2 S cm-1，在柔性锌-二氧化锰电池中可实现303.7 mA h g-1的高比容量。不仅如此，由该电解质组装的电池在经过切割、弯曲或锤击后，单位容量仍能保持原有的84.2%、105%或98.9%，具有出色的抗损伤能力。在压缩和拉伸等形变测试中，电解质表现出了良好的形变能力和可压缩性，并在不断变化的形状和尺寸下保持其稳定性。结果表明，该皮革基凝胶电解质是开发用于柔性可穿戴锌离子电池的有前途的候选者。 With the continuous innovation of the wearable electronics industry, flexible Zn-ion batteries (FZIBs) have attracted much attention in the research of wearable electronics and portable devices due to their advantages of low cost and high safety. In this work, we developed a novel leather-based gel electrolyte (LGE) with high ionic conductivity, good flexibility, and high stability for flexible Zn-ion batteries. At room temperature, the ionic conductivity of this electrolyte is 1.36×10-2 S cm-1, and a high specific capacity of 303.7 mA h g-1 can be achieved in a flexible Zn-MnO2 battery. Moreover, the battery assembled with this electrolyte can still maintain 84.2%, 105% or 98.9% of the original unit capacity after being damaged by cutting, bending or hammering, and has excellent damage resistance. In deformation tests such as compression and tension, the electrolyte exhibits excellent deformability and compressibility, and maintains its stability under changing shapes and sizes. The results suggest that the developed leather-based gel electrolyte is a promising candidate for flexible and wearable Zn-ion batteries.
