随着可穿戴电子产品的微型化发展,开发轻柔、灵活、体积小、能量密度高的柔性储能器件成为研究的热点。以芳纶纳米纤维(aramid nanofiber,ANF)作为纤维增强柱撑材料,采用真空抽滤的方法制备MXene/ANF柔性自支撑电极,避免引入集流体和黏合剂等“死体积”,并将其组装成全固态对称超级电容器。随着ANF含量增加至15%(质量分数), MXene/ANF自支撑电极的拉伸断裂强度增加至151.5 MPa,而电导率降低至1371.1 S/cm,在1 A/g的电流密度下表现出432.7 F/g的高比电容。组装的柔性对称全固态超级电容器的能量密度为25.7 Wh/kg,对应的功率密度为523.1 W/kg,具有优异的柔韧性和长循环寿命(10000周次循环充放电后,电容保持率为88.9%)。 |

With the development of miniaturized wearable electronics,flexible energy storage devices with soft,flexible,small size,and high energy density have attracted widespread attention. Aramid nanofibers (ANF) were utilized as fiber reinforcement and pillared structure materials to prepare MXene/ANF flexible self-supporting electrode through vacuum filtration, which were subsequently assembled into all-solid-state symmetric supercapacitors.With the increase of ANF content to 15%,the mechanical properties of MXene/ ANF self-supporting electrode increase to 151.5 MPa,while the conductivity decrease to 1371.1 S/cm. The MXene/ANF Self-supporting electrode shows a high specific capacitance of 432.7 F/g at the current density of 1 A/g. The assembled symmetric all-solid-state supercapacitors exhibit excellent mechanical flexibility and remarkable cycling stability, with an energy density of 25.7 Wh/kg at the power density of 523.1 W/kg and about 88.9% capacitance retention over 10000 cycles. |
