Abstract

Developing a novel flexible textile-based electrode with splendid electrochemical performance for seamless embedding in smart clothing remains a huge challenge. In this work, amorphous Co–Fe–B alloy@RGO@cotton fabric flexible electrode with outstanding electrochemical properties was prepared through dipping-drying method and chemical reduction method at room temperature. The electrochemical performance of this resultant composite material could be controlled by adjusting the Co/Fe molar ratio. With the molar ratio of Co/Fe 2:1, this flexible electrode demonstrated the maximum specific capacitance 302.6 F/g at the scan rate 5 mV/s. Even after 3000 cycles of charge and discharge or being folded for 300 times, the fabric flexible electrode also maintained the high specific capacitance retention, showing its superior stability and flexibility. In brief, this flexible Co–Fe–B@RGO@cotton fabric electrode with easy fabrication, low-cost, and splendid electrochemical performance offers promising prospects in the field of flexible and wearable electronics.
