Specifically, anions contend against weakly solvating solvents to occupy the LiPS inner solvation shell. Enhancing anion coordination while diminishing weakly solvating solvent coordination overcomes the rate-determining LiPS charge-transfer barriers. As a proof of concept, bis(fluorosulfonyl)imide anion coordination reduces activation polarization and boosts cycling stability at high current densities.
