论文摘要
灵活电子设备的兴起要求具有良好的机械和电化学性能的具有成本效益和可扩展的电池。在这项工作中，我们开发了可打印的，基于聚合物的AGO-ZN电池，具有柔韧性，可再生能力，高面积和低阻抗。使用弹性底物和粘合剂，当前的收集器，电极和分离器可以轻松地逐层屏幕打印，并在堆叠的配置中真空密封。电池的尺寸和容量可自定义，用于主要应用的最高可获得的面积为54 mAh/cm2。高级Micro-CT和EIS用于表征电池，其机械稳定性通过反复的扭曲和弯曲进行了测试。电池被用来为需要高电流排水管的灵活的电子墨水显示系统供电，并且比商业硬币电池的表现出色。开发的电池提供了一种实用的解决方案，可以为各种电子产品提供动力，并对实用和高性能灵活电池的未来开发产生了重大影响。
The rise of flexible electronics calls for cost-effective and scalable batteries with good mechanical and electrochemical performance. In this work, we developed printable, polymer-based AgO-Zn batteries that feature flexibility, rechargeability, high areal capacity, and low impedance. Using elastomeric substrate and binders, the current collectors, electrodes, and separators can be easily screen-printed layer-by-layer and vacuum-sealed in a stacked configuration. The batteries are customizable in sizes and capacities, with the highest obtained areal capacity of 54 mAh/cm2 for primary applications. Advanced micro-CT and EIS were used to characterize the battery, whose mechanical stability was tested with repeated twisting and bending. The batteries were used to power a flexible E-ink display system that requires a high-current drain and exhibited superior performance than commercial coin-cell batteries. The developed battery presents a practical solution for powering a wide range of electronics and holds major implications for the future development of practical and high-performance flexible batteries.
