Abstract High‐performance bifunctional electrocatalyst for oxygen evolution reaction (OER) and reduction (ORR) is the keystone industrialization of rechargeable zinc‐air battery (ZAB). In this work, modulation in spin state Fe single atom on nitrogen doped carbon (Fe 1 ‐NC) devised by Co 3 O 4 (Co @Fe ‐NC), a mediate recorded. Besides, d band center downshifted associated with increment e g filling revealing weakened interaction OH * moiety, resulting boosted ORR performance. The kinetic current density ‐NC 2.0‐ 5.6 times higher than commercial Pt/C, respectively. Moreover, high found contributing to accelerated surface reconstruction witnessed operando Raman electrochemical impedance spectroscopies. A robust OER activity overpotential 352 mV at 50 mA cm −2 achieved, decreased 18 60 comparison @NC IrO 2 . reveals balanced adsorption species its deprotonation leading stability. ZAB performance 193.2 mW maintains 200 h. Furthermore, all‐solid‐state shows promising 163.1
