Zinc‐Air Batteries: A ΔE = 0.63 V Bifunctional Oxygen Electrocatalyst Enables High‐Rate and Long‐Cycling Zinc–Air Batteries (Adv. Mater. 15/2021)

The pursuit for high bifunctional oxygen electrocatalytic activity is the key issue to achieve advanced rechargeable zinc–air batteries. In article number 2008606, Bo-Quan Li and co-workers fabricate a composite noble-metal-free electrocatalyst with bifunctional activity of ΔE = 0.63 V. Such high bifunctional activity greatly refreshes the record by ca. 50 mV and renders extraordinary performances of corresponding rechargeable zinc–air batteries.
