Flexible 2D MXenes for wearable next-generation energy storage applications

The rise of wearable electronics has generated immense opportunity for the researchers to tailor the expanding demand of future electronics. MXenes, a family of two-dimensional (2D) transition-metal carbides and nitrides, exhibit excellent flexibility and other commendable properties, rendering them highly suitable for wearable electronics. This review primarily focuses on the synthesis of MXenes for flexible and wearable application, including methods such as electrospinning, wet-spinning, bi-scrolling, 3D printing, and coating. Furthermore, the review comprehensively discusses the significant advancements and progress made in the field of flexible and wearable MXene-based supercapacitors. It also addresses the challenges and future prospects associated with MXenes as wearable energy storage devices. The integration and development of MXenes-based energy storage devices into other wearable devices holds promise for the future of the electronic industry. © 2024 Elsevier B.V.
