Abstract

Flexible and wearable electronics are poised to revolutionize various domains, but the practical implementation of these devices is hindered by the significant difficulty of energy storage devices. An effective solution can be found in the advancement of high-performance supercapacitors by developing with the qualities of being integrated, elastic, and self-healable, without requiring additional film layers. Hydrogels greatly contributed to achieving this owing to their interesting properties, conductivity, and flexibility. This short review explores the recent progressions in all-in-one supercapacitors powered by hydrogels, highlighting their functional mechanisms of self-healing, ion transmission, and synchronous deformation. We discussed the potential applications in wearable electronics, medical devices, and flexible energy storage systems, focusing on design optimization and new functionalities. Furthermore, we provide insights into future research directions, guiding the exploration of novel additives and achieving high and stable performance.

水凝胶供电的一体化超级电容器:现状与前景
柔性和可穿戴电子设备将给各个领域带来革命性的变化,但这些设备的实际应用却因能量存储设备的巨大困难而受到阻碍。通过开发具有集成性、弹性和自愈性的高性能超级电容器,而无需额外的薄膜层,可以找到有效的解决方案。水凝胶因其有趣的特性、导电性和柔韧性,为实现这一目标做出了巨大贡献。这篇简短的综述探讨了由水凝胶驱动的一体化超级电容器的最新进展,强调了其自修复、离子传输和同步变形的功能机制。我们讨论了在可穿戴电子设备、医疗设备和柔性储能系统中的潜在应用,重点关注设计优化和新功能。此外,我们还深入探讨了未来的研究方向,为探索新型添加剂和实现高稳定性能提供了指导。

期刊介绍: The development of the Current Opinion journals stemmed from the acknowledgment of the growing challenge for specialists to stay abreast of the expanding volume of information within their field. In Current Opinion in Electrochemistry, they help the reader by providing in a systematic manner: 1.The views of experts on current advances in electrochemistry in a clear and readable form. 2.Evaluations of the most interesting papers, annotated by experts, from the great wealth of original publications. In the realm of electrochemistry, the subject is divided into 12 themed sections, with each section undergoing an annual review cycle: • Bioelectrochemistry • Electrocatalysis • Electrochemical Materials and Engineering • Energy Storage: Batteries and Supercapacitors • Energy Transformation • Environmental Electrochemistry • Fundamental & Theoretical Electrochemistry • Innovative Methods in Electrochemistry • Organic & Molecular Electrochemistry • Physical & Nano-Electrochemistry • Sensors & Bio-sensors •
