中文摘要：

柔性电池作为新型柔性电子设备的关键部件,得到越来越多的关注。近年来,柔性锂离子电池取得了实质性的发展,并在卷曲式显示器、触摸屏、可穿戴动力传感器和可植入医疗装置等方面得到应用。本文主要介绍柔性锂离子电池的发展现状,分别从集流体、电极材料和电解质三部分进行阐述,特别介绍拉伸性能的实现途径,根据其不同的结构特点,可以分为波形结构、点阵互联结构、纺织结构、折纸结构和电缆式结构,并提出将柔性材料与新型结构相结合可以促进柔性电池发展。同时,也对其他柔性电池体系,如锂硫电池、燃料电池和太阳能电池等的最新发展进行简单概述。最后,对目前柔性电池的发展过程中存在的问题进行了总结,并对其未来的发展方向与面临的挑战进行展望。

英文摘要：

Flexible batteries have attracted more and more attentions as the key component for the flexible electronic devices.Recently,flexible lithium-ion batteries have been developed quickly and applied to roll-up displays,touch screens,wearable sensors and implantable medical devices.In this review,we mainly focus on recent research of flexible lithium-ion batteries,and summarize how to realize flexibility of each component of the lithium-ion batteries,including current collectors,electrode materials and solid electrolytes.In addition,the structural design strategies for the realization of stretchable character are introduced,which can be divided into Wave-Structural Configuration,Interconnect-Island Mesh Configuration,Textile Structural Configuration,Origami Design Configuration and Cable-Type Configuration according to the different structural features.In order to promote the flexibility of the batteries to a large extent,we propose that the flexible materials should combine with novel stretchable structures.At the same time,we make a brief overview on the latest development for other flexible battery systems,such as lithium-sulfur battery,fuel cell and solar cell.Finally,the existing issues of flexible lithium-ion batteries during their development processes,the forecast the prospects and challenges toward the practical applications of flexible lithium-ion batteries in electronic devices are summarized.
