Abstract

Energy storage textiles represent an innovative form of flexible energy storage devices, fully leveraging the wearing advantages of textiles and demonstrating unique benefits in wearable electronics. However, due to the inherent porous and insulating characteristics of textiles, textiles electrodes suffer from intricate preparation process and unsatisfying performance. Additionally, the electrolytes face challenges such as evaporation loss and leakage. To address these issues, this work presents an innovative strategy for fabricating energy storage garments based on the interfacial crosslinking of hydrogel electrolyte. Garments and electrodes were first assembled with polyvinyl alcohol (PVA) solution. The energy storage textiles are prepared by constructing textile/hydrogel/electrode interfaces during the freezing-thawing crosslinking process with enhanced strength. This strategy avoids the complex step of fabricating textile electrodes. Additionally, the hydrogel is hygroscopic and can replenish moisture from the air, enabling the long-term operation of devices without encapsulation. Importantly, this strategy is versatile and compatible with various textiles and available electrodes. A variety of supercapacitors (SCs) have been successfully integrated into commercial garments, including large-sized devices (5 × 5 cm², 11.8 F) for wearable applications. This innovative strategy is expected to provide new insights for the development of energy storage textiles.

吸湿水凝胶的界面交联：储能服装及其可穿戴应用的通用策略

储能纺织品代表了柔性储能装置的一种创新形式，充分发挥了纺织品的穿着优势，在可穿戴电子产品中展现出独特的优势。然而，由于纺织品固有的多孔性和绝缘性，纺织品电极的制备工艺复杂，性能不理想。此外，电解质还面临蒸发损失和泄漏等挑战。为了解决这些问题，本工作提出了一种基于水凝胶电解质界面交联制造储能服装的创新策略。首先用聚乙烯醇（PVA）溶液组装衣服和电极。通过在冻融交联过程中构建织物/水凝胶/电极界面，制备了具有增强强度的储能纺织品。这种策略避免了制造纺织电极的复杂步骤。此外，水凝胶具有吸湿性，可以从空气中补充水分，使设备无需封装即可长期运行。重要的是，这种策略是通用的，与各种纺织品和可用的电极兼容。各种超级电容器（SCs）已经成功地集成到商业服装中，包括用于可穿戴应用的大尺寸设备（5 × 5 cm2, 11.8 F）。这一创新战略有望为储能纺织品的发展提供新的见解。
