Figure 7. (A) Schematic diagram of the in situ formation of Zn₃(PO₄)₂·4H₂O SEI on Zn anode surface^[237]. (B) Schematic diagram of preferential Sn deposition than Zn in the 7.6 m ZnCl₂ aqueous electrolyte with 0.05 m SnCl₂ additive. The deposited Sn would further facilitate the formation of a uniform zincophobic Zn₅(OH)₈Cl₂·H₂O SEI, and the water activity was decreased due to the strong H₂O-Cl^- interactions^[241]. (C) Schematic illustration of the PEG additive in the electrolyte for uniform Zn deposition. (D) The galvanostatic charge/discharge profile of symmetric cells with 0% or 70% PEG additive^[284]. (E) Schematic diagram of PVIPS gel electrolyte for changing the solvated structure of Zn²⁺ and inducing a Zn (002) texture^[311]. (F) The MD simulation snapshot of ZCE at 300 K illustrating the enhanced ion dynamics and the diagram illustrating the Zn²⁺ hopping-type transport mechanism in the ZCE^[329].
