Tailoring MOF Separator with Enhanced Lithium‐Ion Desolvation for High Sulfur Redox Kinetics in Lithium–Sulfur Batteries

ABSTRACT Ideal separators for rechargeable lithium–sulfur (Li–S) batteries should facilitate Faradaic reactions near the electrode surface while mitigating the shuttle effect. However, conventional separator materials often exhibit sluggish Li + migration rates and reaction kinetics due to their high Li + desolvation energy and diffusion resistance. Investigating the Li + transport mechanism within separators and elucidating Li + desolvation process remains a significant challenge. Herein, we sy
