Abstract The exploration of oxygen catalyst with superior behaviors in a wide temperature range is key issue for Zn–air battery. Herein, the CoN‐CoSe 2 @C hollow cages built‐in electric field (BIEF) on heterointerface are explored as electrocatalyst battery (ZAB). Based theoretical analysis, large work function difference (∆W F ) heterostructure propels interfacial electron redistribution, which results strong BIEF and facilitates high catalytic activities. In addition, nanocrystals embedded carbon nanocage to fully realize its performance. central structure based nanocages provides facile electron/ion/mass pathways endows fast kinetics. Taking advantages both well‐designed substrate, achieve bifunctional electrocatalytic good cycling performance even down low‐temperature such −30 °C. Moreover, full ZAB cage cathode shows reliability diverse working conditions. Therefore, it promising power source candidate electronics practical applications.

Abstract Integrating active sites for oxygen reduction and evolution reactions (ORR OER) is pivotal advancing bifunctional electrodes. Addressing the geometric/electronic properties of these essential to disrupt linear scaling relationship between adsorption desorption complex intermediates. Herein, a proof‐of‐concept presented constructing asymmetric trinuclear employing both composition‐ size‐based coupling strategies. These comprise ORR‐active Fe single atom (Fe SA ), OER‐active atomically clustered species AC Ni as modulators. This AC‐SA ‐Ni @N‐doped carbon exhibits excellent catalytic activities, with narrow potential gap 0.661 V an ORR half‐wave 0.931 OER 1.592 at 10 mA cm −2 . The Zn‐air battery this material achieves peak power density 293 mW , specific capacity 748 mAh g Zn −1 remarkable stability. Experimental findings theoretical simulations reveal that induced strong electronic among centers, facilitating charge redistribution optimizing barriers enhances rapid release * OH during efficient transformation from O OOH OER. study presents novel strategy developing robust
