Recent Advances in MXene-Based Fibers, Yarns, and Fabrics for Wearable Energy Storage Devices Applications

Abstract

With the rapid development of wearable electronic textiles, the study of flexible wearable energy storage devices has been pushed to the forefront. The discovery of two-dimensional (2D) MXene materials provides ideas and materials for the study of flexible wearable energy storage devices. Combining the excellent properties of MXene with a fiber/fabric can provide a good strategy for flexible energy storage equipment and other functional fibers and fabrics. This paper reviews the fabrication of MXene-based fibers/fabrics and their research progress as flexible supercapacitors (SCs). First, this paper discusses the preparation, properties, and development of 2D MXene materials. Then, five methods for manufacturing MXene-based fibers are summarized, and the fiber properties are analyzed, which is very important for the further application of MXene-based fibers. Furthermore, the assembly and performance analysis of MXene-based flexible fiber SCs, fabric SCs, and other types of SCs are reviewed. Finally, the potential, challenges, and future opportunities for the preparation of MXene-based fibers and flexible fiber/fabric SCs are discussed.
