Abstract

Engineering aqueous electrolytes with an ionic liquid (IL) for the zinc (Zn) metal anode has been reported to enhance the electrochemical performances of the Zn metal batteries (ZMBs). Despite these advancements, the effects of IL and the mechanisms involving their anions and cations have been scarcely investigated. Here, we introduce a novel electrolyte design strategy that synergizes anion-cation chemistry using a halogen-based IL and elucidates the underlying mechanism. The strongly and preferentially adsorbed halogen anions guide the formation of a water-poor electrical double layer (EDL) by imidazole-based cations, resulting in the formation of a halide-rich inorganic interphase. This synergistic…
