摘要

中文摘要 柔性可拉伸电子技术是未来可穿戴设备的核心技术,其中柔性可拉伸的储能设备比如锂离子电池或超级电容器是未来集成式可穿戴设备的核心部件之一。现在国内和国际上关于柔性可拉伸电化学储能设备的研究,关键难点在于制备具有“”三高“性能的柔性可拉伸电极:高可拉伸性,高导电性,高电化学稳定性。传统电极比如铜箔等金属片导电性高,但是不具有可拉伸性,而现在研究中的柔性电极都是碳基电极包括碳纳米管,石墨烯等,导电性不够理想,影响了高性能储能器件的制备。本项目提出一种创新性的双层嵌入式电极,结合了碳纳米管的优异电化学稳定性和银纳米线的优异导电性,有望成功克服各自单独使用时的缺点。本项目的研究重点,是探索三个典型体系的电解液在双层电极中的渗透行为,从来建立双层电极在不同的测试条件下的电化学稳定性模型,指导未来高性能柔性可拉伸能源器件的设计和制备。
英文摘要 Stretchable electronics is the key technology for future wearable electronic devices. Stretchable energy storage and conversion devices such as batteries and supercapacitors are among the key components for independent, integrated wearable electronic systems. The most significant challenge for stretchable energy storage device research is the developments of stretchable electrodes with high stretchability, high electrical conductivity and high electrochemical stability. The conventional electrodes such as metal foils have high electrical conductivity but they are typically rigid and not stretchable. The most commonly used stretchable electrodes now are typically carbon-based materials such as carbon nanotubes and graphene. However, carbon-based electrodes are non-ideal in terms of electrical conductivity. We propose in this project an innovative design of double-layer embedded carbon nanotube/silver nanowire stretchable electrodes. The double-layer electrodes combine the merits of high electrochemical stability of carbon nanotubes and high electrical conductivity of silver nanowires. We will focus on the investigations of the penetration behaviors of three types of most commonly used electrolyte systems, and try to establish understandings on the electrochemical stability of the double-layer electrodes, aiming to provide guidance for the future design and fabrication of high performance stretchable energy storage devices.
