Recent Advances on Electrospun Nanomaterials for Zinc–Air Batteries

Abstract

Zinc–air batteries have received increasing attention in energy storage and conversion technologies. However, several challenges still emerge in the development of high‐level zinc–air batteries. In this regard, electrospun materials with unique nanostructures and characteristics are applied in the high‐performance zinc–air batteries. This work reviews recent progress of electrospun technologies for their diverse application in novel zinc anodes, separators, and air cathodes in zinc–air batteries. After a brief introduction, the fundamental principle and technological parameter of electrospinning technology are discussed, and then multifunctional electrospun nanofiber materials including their fabrication procedures, structures, and electrochemical properties are reviewed in the application of zinc–air batteries. Finally, urgent challenges and opportunities are comprehensively proposed for the electrospun nanomaterials in zinc–air batteries. This work intends to offer readable report for electrospun technology toward their application in zinc–air batteries, which inspires more fabrication approaches and material innovations in energy conversion and storage technologies.
