The development of highly active bifunctional electrocatalysts is crucial to the sluggish oxygen reduction reaction/oxygen evolution reaction (ORR/OER) for efficient wearable Zn–air batteries (ZAB). Fe-Nx-C moieties anchored on carbon supports emerge as a desirable alternative ORR catalysts but its OER activity suffers from low catalytic performance and stability. Herein, N-doped carbon-encapsulated Fe3C MnO nanoparticles composite (FeMn-NC) was developed using simple one-step pyrolysis self-sacrificial template. obtained FeMn-NC possess hierarchical porous structure with large specific surface area rich pyridinic N, which are favorable exposure sites. introduction Fe3C/MnO interface can regulate charge redistribution promote ORR/OER kinetics, confirmed by theoretical calculations. exhibits an excellent in alkaline electrolytes.The assembled liquid ZAB cathode achieve ultrahigh capacity 831.7 mAh g-1 charge-discharged stability up 800 h at 10 mA cm⁻² (2400 cycles). Furthermore, corresponding flexible solid-state provides stable open-circuit voltage 1.50 V 676.1 g−1 1.0 cm-2 good cycling This work offers strategy synthesize materials properties, be applied other electrochemical energy devices.
