Abstract
Abstract Aqueous zinc‐metal batteries (AZMBs) usually suffered from poor reversibility and limited lifespan because of serious water induced side‐reactions, hydrogen evolution reactions (HER) and rampant zinc (Zn) dendrite growth. Reducing the content of water molecules within Zn‐ion solvation sheaths can effectively suppress those inherent defects of AZMBs. In this work, we originally discovered that the two carbonyl groups of N‐Acetyl‐ϵ‐caprolactam (N‐ac) chelating ligand can serve as dual solvation sites to coordinate with Zn 2+ , thereby minimizing water molecules within Zn‐ion solvation sheaths, and greatly inhibit water‐induced side‐reactions and HER. Moreover, the N‐ac chelating additive can form a…
