ZIF‐67 In Situ Grown PAN Spun Membrane Gel Electrolyte for Sodium‐Sulfur Batteries

open access: yesCarbon Energy, EarlyView.
This illustration shows the fabrication process of a solid‐state electrolyte for sodium‐sulfur (Na‐S) batteries. First, a polyacrylonitrile (PAN) fibrous membrane is prepared. Next, ZIF‐67 is grown in situ on the PAN membrane to form PAN@ZIF‐67. Subsequently, polyethylene oxide (PEO) is introduced into PAN@ZIF‐67 to obtain the composite electrolyte PEO/
