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.
