Zinc‐Air Batteries In article number 2103622 Qing Wang and co‐workers demonstrate a new Zn‐air battery chemistry based on a quinone‐mediated 2‐electron oxygen reduction reaction (ORR). The kinetic model of the redox‐mediated ORR reaction at different pHs is established along with mechanistic insights. The ultrafast reaction kinetics lead to considerably enhanced energy efficiency when it operates in a Zn‐air flow battery configuration.
