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.
