Fiber micro-supercapacitors provide the advantages such as lightweight, the ease of fabrication into textiles. However, their small capacity for energy storage limits their practical applications. In this study, we fabricate porous fiber electrodes with large surface area through a colloidal crystal for high-performance micro-supercapacitors. Regularly ordered colloidal crystal is used as a template on the surface of carbon fibers. Multiwalled carbon nanotube (MWCNT) aqueous suspension are deposited on the surface, creating the inverse opal structure. The resulting nanostructure fiber electrodes are consolidated with a solid polymer electrolyte, leading to flexible and wearable fiber micro-supercapacitors. Fiber micro-supercapacitors show good capacitance and rate-retention capability as well as long cycle lives. |
