摘　　要：近年来,智能可穿戴设备迅速发展,传统电池受限于材料的刚性难以满足柔性电子器件的需求,亟需开发新型储能设备,目前已有一系列有关可拉伸电池的报道。本文对相关工作进行了总结回顾,将实现电池拉伸性的策略分为设备和部件两个层面,重点对不同维度上实现电池拉伸性的整体结构设计及各可拉伸部件的制备方法进行了综述,并分析了两者的优势与不足,指出了在可拉伸电池研究中所面临的如能量密度、界面退化、封装工艺和设备集成等共性问题,同时对未来的发展趋势进行了展望。Wearable devices have attracted tremendous interest in recent decades,but the rigidity of traditional battery components limits its development.To power up the wearable devices,it is urgent to develop a new type of stretchable energy storage devices.A series of representative stretchable battery preparation methods have been reported.This review summarizes the related works in this field,divides the strategies to achieve stretchability into two categories:device-level and component-level.We focus on the structural design in different dimensions and the preparation methods of each stretchable component to achieve stretchability,analysing the advantages and shortcomings of both ways.The general issues such as energy density,interface degradation,encapsulation process and device integration of the stretchable battery are pointed out,and the future development trend is also foreseen.
