Abstract Solid polymer electrolytes (SPEs) are promising for high‐energy and high‐safety solid‐state lithium metal batteries (LMBs). Here, a polycationic solid electrolyte (PCSE) is described that leverages the inherent high thermal/chemical stability of domain anion trapping (FMAT) effect another fluorinated microdomain stable fast‐charging high‐voltage LMBs. Specifically, while imidazolium backbone ensures segmental flexibility facilitating Li + mobility, effectively traps bis(trifluoromethanesulfonyl)imide anions by strong dipole interactions, imparting localized solvation restricted mobility anions, as well improved oxidation stability. As result, PCSE exhibits ionic conductivity 1.4 mS cm −1 , transference number 0.50, wide electrochemical window ∼5.5 V at 25 °C.

Abstract Modern batteries are highly complex devices. The cells contain many components—which in turn all have variations, both terms of chemistry and physical properties. A few examples: the active materials making electrodes coated on current collectors using solvents, binders additives; multicomponent electrolyte, contains salts, electrolyte can also be a solid ceramic, polymer or glass material; separator, which made fibres, polymeric, composite, etc. Moving up scale these components assembled different formats geometries, coin Swagelok for funamental testing understanding, pouch, prismatic cylindrical application. Given this complexity dictated by so there is no wonder that addressing crucial issue true sustainability an extremely challenging task.
