The increasing developments in wearable electronics demand compatible power sources such as yarn supercapacitors (YSCs) that can effectively perform in a limited footprint. MXene nanosheets, which have been recently shown in the literature to possess ultra-high volumetric capacitance, were used in this study for the fabrication of YSCs in order to identify their potential merit and performance in YSCs. With the aid of a conductive binder (PEDOT-PSS), YSCs with high mass loading of MXene are demonstrated. These MXene-based YSCs exhibit excellent device performance and stability even under bending and twisting. This study demonstrates that MXene is a promising candidate for YSCs and its further development can lead to flexible power sources with sufficient performance for powering miniaturized and/or wearable electronics.

MXene：纱线超级电容器的潜在候选人

穿戴式电子产品的不断发展要求可兼容的电源，例如纱线超级电容器（YSC），这些电源可在有限的占地面积内有效地发挥作用。最近在文献中显示出具有超高体积电容的MXene纳米片被用于本研究中的YSC的制造，以鉴定其在YSC中的潜在优点和性能。借助导电粘合剂（PEDOT-PSS），展示了具有大量MXene负载的YSC。这些基于MXene的YSC即使在弯曲和扭曲下也具有出色的器件性能和稳定性。这项研究表明，MXene是YSC的有前途的候选者，它的进一步发展可以产生具有足够性能的柔性电源，以为小型化和/或可穿戴电子设备供电。
