ABSTRACT
Advanced flexible/wearable electrochemical energy storage devices are much needed for various applications ranging from portable electronics to lightweight electric vehicles/aerospace equipment. Electrospinning is a straightforward and cost-effective approach for the facile fabrication of flexible nanofibers with versatile structures. These as-obtained carbon-based fibers hold great promise in the development of advanced electrochemical energy storage (e.g., supercapacitors and secondary batteries) due to their being lightweight, high electrical conductivity, excellent mechanical strength, flexibility, and tunable electrochemical performance. This chapter summarizes various strategies of structural control for improving the as-obtained carbon-based materials’ mechanical, electrical, and electrochemical performance. Additionally, the remaining challenges and future prospects of electrospinning and electrospun carbon-based materials are proposed.
