Abstract Developing efficient and stable bifunctional oxygen catalysts is essential for addressing the trade‐off between reduction oxidation reactions in rechargeable zinc–air batteries (ZABs). In this work, a novel composite regulation‐enhanced strategy proposed to prepare heterogeneous catalyst, FeCoNiCuMn@NC/NiFeCe LDH, exhibiting exceptional activity. The catalyst achieves half‐wave potential of 0.905 V reaction 266 mV overpotential at 10 mA cm −2 evolution reactions. Experimental theoretical analyses reveal that interface FeCoNiCuMn@NC NiFeCe LDH effectively optimizes electronic structure materials by shifting d‐band center closer Fermi level. This optimization not only enhances continuous distribution density but also improves adsorption desorption processes intermediates, thereby overcoming activity stability. When applied ZABs, demonstrates remarkable cycling stability over 750 h peak power 268.5 mW·cm . study lead breakthrough design, significantly advancing ZABs inspiring new strategies diverse energy storage conversion systems.
