Abstract Rechargeable Zn–air batteries (ZABs) are promising for energy storage and conversion. However, the high charging voltage low efficiency hinder their commercialization. Herein, these challenges addressed by employing precisely constructed multifunctional Fe–Co diatomic site catalysts (FeCo‐DACs) integrating iodide/iodate redox into ZABs to create Zinc–air/iodide hybrid (ZAIHBs) with highly efficient catalyst. The strong coupling between 3d orbitals of Fe Co weakens excessively binding strength active sites intermediates, enhancing catalytic activities oxygen reduction/evolution reaction redox. Consequently, FeCo‐DACs exhibit outstanding bifunctional activity a small potential gap (Δ E = 0.66 V) stability. Moreover, an performance toward is obtained. Therefore, FeCo‐DAC‐based ZAIHBs up 75% at 10 mA cm −2 excellent cycling stability (72% after 500 h). This research offers critical insights rational design DACs paves way high‐energy devices.
