Electrospining Machine: Recent advances in Electrospun Nanofbers for aqueous zinc ion batteries

Literature introduction

Aqueous zinc ion batteries (AZIBs) are considered one of the most promising large-scale energy storage systems due to their high energy density and inherent safety. However, the severe dendrite growth of the zinc anode, the severe degradation of the anode, and the boundedness of the diaphragm limit the application of AZIBs. nanofber machime, with the advantages of controllable nanostructures, high electrical conductivity, and large specific surface area, has a great potential and a broad application prospect for constructing AZIBs with excellent electrochemical properties.
