Abstract Li‐O 2 batteries urgently needs high discharge capacity and stable cycling performance, requiring effective reliable bifunctional catalysts for the oxygen reduction reaction (ORR) evolution (OER). Herein, Hovenia acerba Lindl ‐like heterostructure composed of cobalt sulfide tin dioxide supported on carbon substrate (CoS/SnO @C) is prepared via CO laser irradiation technology. The half‐wave potential CoS/SnO @C ORR 0.88 V, while overpotential OER at 10 mA cm −2 as low 270 mV. employing catalyst displays a specific 3332.25 mAh g −1 long life 226 cycles. Additionally, theory calculations demonstrate that construction decreases energy barrier rate‐determining step (RDS) both OER. Notably, SnO behaves electronic promoter to optimize structure interface triggers charge redistribution CoS, which weakens adsorption strength * O‐intermediates allows break linear scaling relationship, thus further enhancing catalytic performance @C. This research furnishes directions design heterogeneous catalysts, highlighting its great application in rechargeable batteries.
