Multifunctional Crown Ether Additive Regulates Desolvation Process to Achieve Highly Reversible Zinc‐Metal Batteries

Abstract Aqueous zinc‐ion batteries have garnered significant attention due to their abundant materials, low production costs, and safety. However, these batteries suffer from severe side reactions, which are closely associated with the presence of a substantial amount of solvent at the electrode surfaces. Herein, 1,4,7,10,13,16‐hexaoxacyclooctadecane (18‐crown‐6) is added to the electrolyte to illustrate both theoretically and experimentally its contribution to the rapid desolvation aspect. It is shown that the addition of 18‐crown‐6 to the electrolyte greatly facilitates the desolvation of the solvated structure and prevents the collection of solvent molecules on the surface of zinc anode, thus inhibiting…
