One-dimensional (1D) fiber electrodes for supercapacitors (SCs) are attracting much attention with their design versatility capable to integrate with the next generation of flexible and wearable electronics and the intrinsic properties of SCs including high power density, exceptional round trip efficiency, long cycle life, low manufacturing cost, and intrinsic safety. Here, using commercially available carbon fibers, we create highly flexible and mechanically robust composite fibers as electrodes for fiber micro-SC applications. The fibers are prepared by a colloidal crystal template-assisted deposition of multi-walled carbon nanotubes on carbon fiber surface. The resulting fibers are highly conductive and readily applicable to fabricating electrodes into a miniaturized architecture. We envisage that the fiber electrodes made out of carbon composites in this study would be suitable for integrating into various macroscopic materials for wearable and flexible energy storage.
