Rechargeable zinc-air batteries afford great potential toward next-generation sustainable energy storage. Nevertheless, the oxygen redox reactions at air cathode are highly sluggish in kinetics to induce poor efficiency and limited cycling lifespan. Air cathodes with asymmetric configurations significantly promote electrocatalytic of loaded electrocatalysts, whereas rational synthetic methodology effectively fabricate remains insufficient. Herein, a strategy interface preconstruction is proposed for high-performance rechargeable batteries. Concretely, preconstructed by introducing immiscible organic-water diphases within cathode, which electrocatalysts situ formed achieve an configuration. The as-fabricated realize high working rates 50 mA cm-2 , long stability 3400 cycles 10 over 100 under harsh conditions 25 mAh . Moreover, universal many systems can be easily scaled up. This work provides effective advanced promotes performance
