Abstract Lithium–sulfur (Li–S) batteries are gaining tremendous attention as promising energy storage solutions due to their impressive density and the affordability of sulfur. However, practical use Li–S encounter major obstacles such polysulfide shuttle effect, which leads capacity loss decreased cycling stability. Herein, a polyethylene imidazole/polyacrylonitrile (PVIMPAN) nanofibers‐modified Celgard separator is constructed via facile electrospinning strategy used polysulfides barrier for batteries. The electron‐deficient imidazole groups introduced on surface PVIMPAN separators create that prevents shuttling extends cycle life. Additionally, developed exhibits significantly enhanced Li + transfer number 0.60, compared commercial (0.20). This enhancement can be attributed strong binding between bis(trifluoromethanesulphonyl)imide anion, leading improved plating stripping performance. Consequently, incorporating into enable achievement discharge 786.0 mAh g −1 with close 100% Coulombic efficiency after 500 cycles at 1C (25 °C). It believed this work provide valuable insights designing suitable robust metal–sulfur

Abstract Homogeneous Li‐ion flux is a significant precondition of uniform deposition in Li metal batteries (LMBs). Numerous methodologies have been presented for homogenizing before based on the features deposition. Separators that provide transfer channels and are directly exposed to anodes attracted rising attention their role guiding regular distribution. More novel functional separators proposed aiming achieve dendrite‐free Herein, factors strategies regulate distribution through toward LMBs concentrated on. The current mechanisms regulation by first highlighted, including physical properties, interactions with electrolyte, modification solid‐state electrolyte interphase. According these mechanisms, separator regulating divided into three methodologies, typical examples introduced. Finally, limitations suggestions future studies presented, inspire engaged researchers newcomers trigger more exciting works this area.
