摘　　要：可穿戴设备等便携式电子产品柔性化、轻薄化的发展需求,使柔性电池受到越来越多研究者的关注。由于锂电池是各类电子产品的主要电源,高比能可拉伸柔性锂电池的开发成为研究重点。锂电池的柔性化结构设计是为了满足电池进行编织织造或在复杂形变条件下的使用需求,在仿生、折纸/剪纸、纤维/纱线等概念启发下,采用柔性或非柔性材料对电池整体结构进行柔性化设计,制备各种形状结构的具有宏观柔性的锂电池。本文综述了锂电池柔性化结构设计的研究进展,分析并探讨了目前存在的问题,以期为未来高能量密度柔性锂电池在可穿戴设备上的应用提供理论指导。With the increasing demand for flexible,lightweight and portable electronic products such as wearable devices,the flexible batteries become more and more attractive for researchers.As lithium battery is the main power supply in all kinds of electronic products,the development of flexible lithium battery with high energy density becomes a hot topic in this field.Lithium battery with flexible structure is designed to meet the needs of battery in weaving or being used under complex deformation.Inspired by concepts of bionics,origami/kirigami,textilefiber/yarn and so on,researchers used flexible or non-flexible materials to design the overall structure of the battery.At the same time,the macro-flexibility battery with variety of structures are designed.This paper described recent progress in researches about flexible structure design for lithium batteries,and discussed the existing problems of macro-structure design,so as to provide a theoretical guidance for the application of high energy density flexible lithium battery in wearable devices in the future.
