Anchoring and boosting: Ferrocene-based separators used to eliminate the polysulfide shuttle effect for Li–S batteries

, 2023
The commercialization of Li–S batteries has been seriously hampered by the infamous “shuttle effect” of soluble lithium polysulfide intermediates (LiPSs, Li2Sx, 4 ≤ x ≤ 8) and sluggish sulfur species conversion kinetics. In this work, vinyl ferrocene and
