Abstract Integration of different active sites by heterostructure engineering is pivotal to optimize the intrinsic activities an oxygen electrocatalyst and much needed enhance performance rechargeable Zn–air batteries (ZABs). Herein, a biphasic nanoarchitecture encased in situ grown N‐doped graphitic carbon (MnO/Co‐NGC) with heterointerfacial are constructed. The density functional theory model reveals formation lattice bridged pyridinic nitrogen atoms anchored Co species, which facilitate adsorption intermediates. Consequently, well‐designed catalyst accessible sites, abundant vacant coupling effects, simultaneously accelerate electron/mass transfer thus promotes trifunctional electrocatalysis. assembled aqueous ZAB delivers maximum power ≈268 mW cm −2 specific capacity 797.8 mAh g zn −1 along excellent rechargeability extremely small voltage gap decay rate 0.0007 V h . Further, fabricated quasisolid‐state owns remarkable 163 long cycle life, outperforming benchmark air‐electrode many recent reports, underlining its robustness suitability for practical utilization diverse portable applications.
