摘要
Abstract The corrosion, parasitic reactions, and aggravated dendrite growth severely restrict development of aqueous Zn metal batteries. Here, we report a novel strategy to break the hydrogen bond network between water molecules and construct the Zn(TFSI) 2 ‐sulfolane‐H 2 O deep eutectic solvents. This strategy cuts off the transfer of protons/hydroxides and inhibits the activity of H 2 O, as reflected in a much lower freezing point (<−80 °C), a significantly larger electrochemical stable window (>3 V), and suppressed evaporative water from electrolytes. Stable Zn plating/stripping for over 9600 h was obtained. Based on experimental characterizations and theoretical simulations, it has been proved that sulfolane can effectively regulate solvation shell and simultaneously build the multifunctional Zn‐electrolyte interface. Moreover, the multi‐layer homemade modular cell and 1.32 Ah pouch cell further confirm its prospect for practical application.
