Stimulus-responsive energy storage devices have recently gained attention due to the increasing demand for safe batteries and smart electronics. Polymers, the most typical stimulus-responsive materials, can change their conformation in response to external stimuli by forming and destroying secondary forces. Although the applications of stimulus-responsive functions in rechargeable batteries are still in the early stage, new concepts of regulating polymer structures have been developed. This review discusses the recent progress of stimulus-responsive polymers on energy storage devices, focusing on the structural transformations of polymers and their impact on battery performance. Future research directions and current limitations of stimulus-responsive polymers for energy storage devices are also presented.
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.
