ABSTRACT
Carbon-based fibers display their advantages in flexible and portable supercapacitors due to their satisfactory electrical conductivity, high surface area, excellent mechanical strength, and controllable material shaping. This chapter first reviews the typical technologies and strategies for the fabrication of main carbon-based fibers of graphene (oxide) fibers, carbon nanotube fibers, and carbonaceous fibers. Then, the unique configurations of supercapacitors assembled from carbon-based fibers are explained in detail to emphasize their peculiarity. Afterward, this chapter summarizes the research status of carbon-fiber electrodes and carbon composite-fiber electrodes with clear classification, as well as the reported efficient modifications and designs for optimizing overall performance. Finally, the challenges and prospects of carbon-based fibers for supercapacitors are discussed.
