中文摘要：

超级电容器,也称电化学电容器,它具有比锂离子电池更高的功率密度和更长的循环寿命,与此同时,其能量密度也高于传统的电介质电容器,因此成为了一类具有很大应用前景的能量储存设备。随着人们对智能电子设备性能要求的提高,各类柔性可穿戴电子设备相继出现,柔性超级电容器作为一类便携式能量储存设备也受到了许多研究者的关注。在持续的研究中,二维平面结构的柔性超级电容器得到较大发展并日益成熟,与此同时,随着对柔性电子设备可穿戴性能要求的提高,一维纤维结构的柔性超级电容器应运而生,并且得到了初步发展。本文首先介绍了超级电容器的储能原理和重要性能的评估方法;接着,重点概述了二维平面结构和一维纤维结构两类柔性超级电容器器件结构和电极材料的研究进展;最后,总结了两类柔性超级电容器仍然存在并亟待解决的问题以及未来发展所面临的关键技术挑战,期望能为柔性超级电容器的研究提供参考和借鉴。

英文摘要：

Supercapacitor（SC）,also called electrochemical capacitor,which has higher power density and longer cycling life than lithium ion battery as well as higher energy density than dielectric capacitor,is a kind of promising energy storage device. The different kinds of flexible and wearable electronic devices are emerging with consumers＇ increasing requirements for electronic devices. Flexible SC,which is a kind of portable energy storage device,has attracted much attention. The two-dimensional planar-structure and one-dimensional fiber-shaped SCs have been developed rapidly with the flexible electronic devices advancing. In this review,the energy storage mechanism of SCs,the diverse performance metrics and evaluation for SCs as a foundation are first introduced to understand different research approaches. Then,the current state-of-the-art progress in devices＇ structure design and electrode materials fabrication of the flexible two-dimensional planar-structure and one-dimensional fiber-shaped SCs are summarized. Last,perspectives on the future development of flexible SCs and highlighted key technical challenges with hope of stimulating further research progress are presented.
