摘　　要：Stimulus-responsive energy storage devices,which can respond to external stimuli,such as heat,pH,moisture,pressure,or electric field,have recently attracted intensive attention,aiming at the ever-increasing demand for safe batteries and smart electronics.The most typical stimulus-responsive materials are polymers that can change their conformation by forming and destroying secondary forces,including hydrogen bonds and electrostatic interactions in response to external stimuli,accompanied by changes in the intrinsic properties such as conductivity and hydrophobicity.Although the applications of stimulus-responsive functions in rechargeable batteries are still in the early stage because of the complexity and compatibility of battery architectures,many new concepts of regulating the polymer structures upon applications of stimuli have already been developed.In this review,we discuss the recent progress of stimulus-responsive polymers on energy storage devices featuring thermal protection and intelligent scenarios,with a focus on the detailed structural transformations of polymers under a given stimulus and the corresponding changes in battery performance.Finally,we present perspectives on the current limitations and future research directions of stimulus-responsive polymers for energy storage devices.随着人们对高安全性电池和智能电子产品的需求日益增长,能够对诸如热、pH值、湿度、压力或电场等外部刺激作出响应的刺激响应能量存储装置引起了广泛关注.最典型的刺激响应材料是聚合物,对于外界刺激它可以通过形成和破坏包括氢键和静电相互作用在内的二次作用力来实现其构型变化,进而产生电导率和疏水性等内在性质的改变.由于电池内部结构组成的复杂性和兼容性等问题,刺激响应功能在可充电电池中的应用还处于起步阶段,但许多针对外部刺激来调节聚合物结构的新概念已经出现.本文综述了近年来聚合物材料在储能装置的热防护和智能化方面的研究进展,重点介绍了聚合物材料在外界刺激下的结构转变及其对电池性能的影响.最后,本文展望了用于储能装置的刺激响应聚合物材料目前的局限性以及未来的发展方向.
