Continuous carbon nanofiber bundles with tunable pore structures and functions for weavable fibrous supercapacitors

A new and efficient strategy is developed for producing one-dimensional flexible carbon nanofiber yarns on a large scale and in a controlled manner, by the coupling of liquid receiver-mediated electrospinning and pyrolysis. Versatile polymer-based materials can therefore be used as precursors for the preparation of carbon nanofiber yarns with tunable pore structures and functions, which endows the resultant fiber supercapacitors with unprecedented electrochemical performance such as high length-specific capacitance and excellent rate capability.209
