Flexible Electrospun Polyacrylonitrile/ZnO Nanofiber Membrane as Separator for Sodium-Ion Batteries with Cycle Stability

In sodium-ion batteries, the research of electrode and separator materials must work in tandem. However, the existing separators still need to go through a drawn-out procedure in order to satisfy the engineering and technological standards of sodium-ion batteries. A new sodium-ion battery separator was created for this investigation. Electrostatic spinning was used to create polyacrylonitrile (PAN)/ZnO nanofiber films, and varying the ZnO nanoparticle doping level enhanced the nanofiber separator’s cyclic stability. A new flexible PAN separator for sodium-ion batteries is presented in this study. It has good commercial value and may find use in flexible, high safety sodium-ion battery systems. Additionally, it offers some theoretical direction for creating organic polymer separators with excellent safety.
