Soft materials for wearable supercapacitors

Abstract

Along with the rapid progress of wearable and portable electronic devices including electrical sensors, flexible displays, and health monitors, there is an ever-growing demand for wearable power sources. Supercapacitors, as a new kind of energy storage device, have received considerable attention for decades due to their high power density, excellent cycling stability, and easy fabrication. To fulfill the demand of wearable power sources, wearable supercapacitors are also further developed and studied. New electrode materials that play a significant role in determining both the wearability and electrochemical performance of wearable supercapacitors are also extensively explored. Herein, the recent progress on wearable soft electrode/electrolyte materials and the structure design strategies for developing wearable supercapacitors are summarized. Additionally, the existing challenges in current technologies and research are highlighted and discussed with the hope of inspiring future studies.
