摘要

有效设计和构建坚固、柔性、高电化学性能的分层纳米结构纤维电极是可穿戴储能装置的关键。本文采用湿纺丝法制备了细菌纤维素（BC）插层Ti3C2Tx （BCT）纤维，用于纤维形超级电容器（FSC）。BC可以显著阻碍Ti3C2Tx薄片的自堆积，形成多孔结构，并连接相邻的Ti3C2Tx薄片，形成较高的机械强度。因此，BCT光纤在三电极系统中具有高电容和良好的速率性能。此外，基于BCT光纤的组装对称FSC具有良好的质量电容和优异的能量密度，在智能可穿戴系统中具有广阔的应用前景。

Bacterial cellulose/Ti3C2Tx MXene hybrid fiber for high-performance flexible fiber-shaped supercapacitors

Effective design and construction of robust, flexible and highly electrochemical fiber shaped electrode with hierarchical nanostructures are critical for wearable energy storage device. Here, bacterial cellulose (BC) intercalated Ti₃C₂T_x (BCT) fiber was fabricated by wet spinning method for fiber shaped supercapacitors (FSC). BC can significantly impede the self-restacking of Ti₃C₂T_x flakes causing a porous structure and connect the adjacent Ti₃C₂T_x sheets constructing high mechanical strength. As a result, the BCT fiber provides high capacitance and good rate performance in three-electrode system. Moreover, the assembled symmetrical FSC based on BCT fiber presents favorable mass capacitance and excellent energy density, demonstrating a bright future in smart wearable system.
