Published: Feb. 17, 2025

Abstract Aqueous zinc‐ion batteries (AZIBs), candidates for large‐scale energy storage, face limitations due to the poor reversibility of zinc anodes. It reports on pyridine derivatives with high donor characteristics, including 2‐chloro‐1‐methylpyridinium iodide (CMPI) and pyridine‐2‐acetaldoxime methyl (PAMI), as effective additives. At lower concentrations, these additives markedly curtail dendrites formation evolution hydrogen anode, thereby prolonging AZIBs life. Through a combination theory experiments, impact side‐chain groups kinetic process depositioni is elucidated. In contrast PAM + , CMPI demonstrates enhanced adsorption self‐assembles at anode‐electrolyte interface, forming barrier free water protective ZnI layer via I − ion integration. This dual‐layer strategy boosts plating/stripping by 100‐fold achieves coulombic efficiency 99.7% in zinc–copper half‐ batteries.
