Abstract Flexible electrodes applied in the field of smart wearable products have attracted intense attention. Textile-based electrodes are considered as promising candidate because of their super flexibility and comfort. Recently, amorphous transition metal boride has been introduced in this application. However, the electrochemistry of amorphous FeB has not been systematically studied. To address this problem, the novel amorphous FeB/RGO/cotton flexible electrodes with multidimensional hierarchical structure were firstly prepared with dipping-drying and chemical reduction methods. The preparation methods are simple and cost-effective at room temperature and atmospheric pressure. The concentration of FeB played the key impact on the structure forming process and electrochemical property. Results showed that FeB/RGO/cotton ternary systems exhibited the better

specific capacitance than corresponding binary systems. When the scan rate was 5 mV/s, the specific capacitance of these flexible electrodes was up to 203.3 F/g. In addition, these electrodes also exhibited superior cyclic stability and flexibility due to high specific capacitance retention (over 100%). In brief, this paper provides a novel idea for the application of flexible cellulose electrode materials with a novel developing material.

Introduction Wearable and flexible electronic devices have aroused tremendous attention due to their light weight and increasing demand in the field of smart garments, flexible displays and biomonitoring implants (Li et al. 2019a, b; Tebyetekerwa et al. 2019). Therefore, designing and constructing flexible energy supplying device has become the critical route to support the development of wearable electronic devices. Supercapacitors with salient flexibility, high energy density, fast charge-discharge capability, and long-life time are regarded as one of the most promising energy storage devices (Li et al. 2018a; Tseng et al. 2018; Wang et al. 2019a). To prepare high-performance supercapacitors, suitable and flexible electrode with
