Abstract

Soft electronics for biomedical and wearable applications have advanced rapidly in recent years, yet their power delivery relies on rigid battery packs, limiting the development of thin-film electronic devices. In this work, we present the design and fabrication of an intrinsically stretchable thin-film organic rechargeable Na-ion battery via addressing the fundamental materials challenges, enabled by the biocompatible and eco-friendly organic Na-ion electrochemistry, rational design of a solvent-resistant stretchable current collector, a strain-adaptable gel polymer electrolyte based on a dynamic polymer framework, and composite electrodes with tunable modulus, by introducing a dual-network polymerization strategy. Collectively, these advancements yield an elastic battery cell maintaining 85% capacity at 30% strain with a Coulombic efficiency (CE) near 100%, stable cycling with 93.6% capacity retention for 130 cycles, and a high CE above 99.8% at 2C. Overall, it presents a promising platform for next-generation thin-film stretchable power sources for wearable and biomedical electronic devices.

一种内在可拉伸的薄膜有机可充电钠离子电池，可用于可穿戴设备

近年来，用于生物医学和可穿戴应用的软电子技术发展迅速，但它们的电力传输依赖于刚性电池组，限制了薄膜电子设备的发展。在这项工作中，我们提出了一种内在可拉伸薄膜有机可充电钠离子电池的设计和制造，通过解决基本材料的挑战，通过生物相容性和生态友好的有机钠离子电化学，合理设计耐溶剂的可拉伸集热器，基于动态聚合物框架的应变适应性凝胶聚合物电解质，以及具有可调模量的复合电极。通过引入双网聚合策略。总的来说，这些进步产生了弹性电池，在30%的应变下保持85%的容量，库仑效率（CE）接近100%，稳定循环130次，容量保持率为93.6%，在2C时的CE高于99.8%。总的来说，它为可穿戴和生物医学电子设备的下一代薄膜可拉伸电源提供了一个有前途的平台。
