摘　　要：轻便灵活的柔性超级电容器在可穿戴和便携式电子储能装置中有着潜在的应用前景。碳材料因具有优异的柔韧性、良好的导电性和较大的比表面积,通常在柔性超级电容器中发挥着柔性基底和导电活性填料的作用。本文首先综述了双电层、赝电容以及混合型超级电容器的储能机理。其次分别介绍了以碳材料作为柔性基底和导电活性填料的最新研究进展。碳材料作为柔性基底复合赝电容材料时,既可以提供大的比表面积,也可为氧化还原反应提供大量活性位点;而作为其他柔性基底的导电活性填料时,既能够改善赝电容材料稳定性的问题,也为电解质离子提供传输通道。文章最后提出了当下柔性超级电容器电极在力学性能、制备方法和评价标准中面临的相关问题。Flexible supercapacitors show potential applications in wearable and portable electronic energy storage devices. Carbon materials usually serve as flexible substrate and conductive active filler in flexible supercapacitors due to their excellent flexibility, high conductivity and large specific surface area.Hence, this paper reviewed three energy storage mechanisms in supercapacitors, the double electric layer,the pseudocapacitor and the hybrid. The latest research progress of carbon materials as flexible substrate and conductive filler was introduced in the following part, respectively. According to three energy storage mechanisms, the analysis of carbon materials as flexible substrate and pseudocapacitance materials can provide not only large specific surface area, but also a large number of active sites for redox reaction. As a conductive filler, it can improve the stability of pseudocapacitance materials and transport channel for electrolyte ions. Finally, the main problems of current electrode design in terms of mechanical properties,preparation methods and evaluation standards were presented.
