Electrospun Nanofibers

Electrospun nanofibers have been considered promising separator candidates for lithium–sulfur (Li–S) batteries due to their unique properties, including but not limited to their high surface area, superior surface-to-volume ratio, excellent flexibility, good mechanical performance, etc. This chapter aims to provide an overview of research in electrospun nanofibers with their applications in Li–S batteries. It starts with a brief introduction to Li–S batteries, followed by the principle and advantages of electrospun nanofibers performed in this area. Applications of electrospun separators in Li–S batteries have been further discussed in detail. In the end, a future vision regarding challenges and perspectives is proposed to provide insightful comments in this field. It is believed that this chapter will provide an extensive and comprehensive reference to utilize this advanced technique to generate novel nanofiber separators for next-generation Li–S batteries.
