Abstract To address the slow kinetics of Li 2 O formation and unwanted effects by‐product CO 3 in lithium‐air batteries (LABs), it is crucial to develop high‐efficiency stable catalytic materials. This study presents application coherent Bi Te @Sb heterostructures with exposed (001) facets as a catalyst LABs. Theoretical analysis reveals that difference work function between Sb leads electron rearrangement at interfaces, forming built‐in electric field. results an asymmetric charge distribution atoms, which enhances adsorption capacity intermediate products promotes growth discharge products. Furthermore, boosts transfer adsorbed molecules heterostructure, increasing overall electrical conductivity system facilitating subsequent reaction process. Additionally, low lattice mismatch heterojunction structural stability ensuring cycling for LABs ‐based cathode achieve 635 cycles pure oxygen 537 air ambient. this end, provides insights into applications heterojunctions potential modulation highly
