Abstract Aluminum air batteries (AABs) are a desirable option for portable electronic devices and electric vehicles (EVs) due to their high theoretical energy density (8100 Wh K −1 ), low cost, safety compared state‐of‐the‐art lithium‐ion (LIBs). However, numerous unresolved technological scientific issues preventing AABs from expanding further. One of the key is catalytic reaction kinetics cathode as fuel (oxygen) AAB reduced there. Additionally, performance price an directly influenced by electrode integrated with oxygen electrocatalyst, which thought be most crucial element. In this study, we covered chemistry well brief discussion mechanistic insights active catalysts how they catalyze enhance reactions. There also extensive research into electrocatalytic materials that outperform Pt/C such nonprecious metal catalysts, oxide, perovskites, metal‐organic framework, carbonaceous materials, composites. Finally, provide overview present state, possible future direction cathodes in AABs.

Abstract Catalysts for zinc‐air batteries (ZABs) must be stable over long‐term charging‐discharging cycles and exhibit bifunctional catalytic activity. In this study, by doping nitrogen‐doped carbon (NC) materials with three metal atoms (Fe, Ni, Cu), a single‐atom‐distributed FeNiCu‐NC catalyst is prepared. The includes Fe(Ni‐doped)‐N 4 the oxygen evolution reaction (OER), Fe(Cu‐doped)‐N reduction (ORR), NiCu‐NC structure (ORR) in nanoparticles. This single‐atom distribution enhances If trimetallic designed, it will surpass typical bimetallic catcalyst. exhibits outstanding performance as an electrocatalyst, half‐wave potential ( E 1/2 ) of 0.876 V versus RHE, overpotential j = 10 253 mV RHE at mA cm −2 , small gap ΔE 0.61 V). As anode ZAB, can undergo continuous charge‐discharged 575 h without significant attenuation. study presents new method achieving high‐performance, low‐cost ZABs via doping.
