Screen-printed MXene-based all-solid-state textile supercapacitors

Textile-based supercapacitors (TSCs) have drawn increasing attention in recent years owing to their potential applications in wearable electronics. However, it remains a critical challenge to increase the energy density of TSCs. Herein, we develop a screen-printing strategy to scalable construct high-performance MXene-based all-solid-state textile supercapacitors, which exhibit excellent electrochemical performance, including high specific capacitance (4979.2 mF cm−2) and energy density (62.2 µWh cm−2). The electrochemical performance of assembled MXene-based TSCs is superior to the-state-of-the-art TSCs. This work provides a new strategy for fabricating high-performance flexible supercapacitors and paves the way for the development of wearable energy storage devices.
