Batteries &Supercaps, Volume 9, Issue 8, August 2026.A physics‐based transmission line model translates the internal architecture of a vanadium flow battery—ion‐selective membrane, electrolyte‐filled carbon‐felt pores, and diffusion layer— into its impedance spectrum. This general, top‐down framework reproduces measured spectra across membrane type, flow rate, and state of charge, and simplifies to a ...

ChemSusChem, Volume 19, Issue 14, 29 July 2026.Benzenesulfonyl fluoride (BF) regulates the transformation of lithium polysulfides (LiPSs) through its sulfur–fluoride exchangeable moiety. Leveraging its chemoselectivity, BF promotes the selective reduction of LiPSs (Li2S8 → Li2S4) while suppressing undesired side reactions, a behavior not observed in the absence of the additive.
