Abstract Seawater electrolyte‐based zinc‐air batteries (S‐ZABs) are considered the promising choice for highly efficient marine power supply, owing to their high specific energy, low cost, and eco‐friendliness. However, air‐cathode suffers from sluggish oxygen reduction reaction (ORR) kinetics together with severe adsorption of Cl − in seawater electrolytes, which severely limits service life efficiency S‐ZABs. Herein, precisely decorating axially coordinated ions (Cl ) on Fe atomic sites (Cl‐Fe SA /NC) construct a local negatively charged interface inhibit is proposed, exhibits desirable ORR activity, good stability almost no loss electrocatalytic performance after long‐term test. Moreover, assembled battery achieves peak density 208.0 mW cm −2 , 1.45 times higher than commercial Pt/C‐based Density functional theory calculations reveal that not only constructs corrosion poisoning active by but also regulates electronic states optimize adsorption/desorption energy intermates, thus improving activity Cl‐Fe /NC.
