在各种储能系统中，超级电容器由于其高功率密度、长循环寿命和快速充放电过程而被认为是最有前途的电池替代品。特别是，柔性电化学超级电容器以其独特的优势，如柔性，形状一致性和重量轻，正在吸引越来越多的关注，以满足现代储能市场对便携式和可穿戴电子设备的当前要求。本文从柔性电极材料的角度综述了柔性全固态超级电容器的最新研究进展。讨论了碳纳米管、石墨烯、赝电容等柔性电极材料，并对其性能进行了综合分析。此外，综述了提高能量和功率密度策略的最新进展。提出了多功能集成系统的进一步研究目标和实现理想化柔性储能系统所面临的挑战。
Among the various energy storage systems, supercapacitors are considered to be the most promising alternative to batteries due to their high power density, long cycle life and fast charge–discharge process. Especially, flexible electrochemical supercapacitors with their unique advantages such as flexibility, shape-conformability, and light weight are attracting ever-increasing attention to meet the current requirements for portable and wearable electric devices in modern energy storage markets. In this perspective, we summarize the most recent progress in flexible all-solid supercapacitors from the point of view of flexible electrode materials. Various flexible electrode materials like carbon nanotubes, graphene, and pseudo capacitive materials are discussed and their performance is comprehensively analyzed. In addition, an overview of the latest progress in strategies to improve the energy and power density is discussed. Further research targets in multifunctional integrated systems and challenges in realizing idealized flexible energy storage systems are also proposed.
