Yarn‐shaped supercapacitors (YSCs) once integrated into fabrics provide promising energy storage solutions to the increasing demand of wearable and portable electronics. In such device format, however, it is a challenge to achieve outstanding electrochemical performance without compromising flexibility. Here, MXene‐based YSCs that exhibit both flexibility and superior energy storage performance by employing a biscrolling approach to create flexible yarns from highly delaminated and pseudocapacitive MXene sheets that are trapped within helical yarn corridors are reported. With specific capacitance and energy and power densities values exceeding those reported for any YSCs, this work illustrates that biscrolled MXene yarns can potentially provide the conformal energy solution for powering electronics beyond just the form factor of flexible YSCs.

高性能双卷MXene /碳纳米管纱线超级电容器

纱线形状的超级电容器(YSC)一旦集成到织物中,就可以满足可穿戴和便携式电子产品不断增长的需求,提供了有希望的储能解决方案。然而,在这种装置形式中,在不损害灵活性的情况下实现出色的电化学性能是一个挑战。在此,据报道,通过采用双辊方法,利用高度分层和伪电容的MXene片材(被困在螺旋形纱线通道中),制造出具有柔韧性的纱线,该MXene型YSC既具有柔韧性又具有出色的储能性能。由于比电容,能量和功率密度值超过任何YSC所报告的值,这项工作表明,双卷MXene纱线不仅可以提供柔性YSC的形状系数,还可以为电子设备提供保形的能量解决方案。
