Abstract
The pursuit of higher energy density for electrochemical energy storage systems has directed attention towards rechargeable metal-air battery chemistries, all of which function based on reversible oxygen redox, i.e., oxygen evolution and reduction reactions. This renders electrocatalyst an essential functional component, with the design/development of efficient-cum-stable electrocatalysts assuming enormous importance. However, these battery chemistries have challenges, such as the passivation of catalysts and dendrite growth at the metal anode. In this regard, after introducing the mechanistic aspects of metal-air battery chemistry, in general, the review discusses the chemistries in more specific terms, followed by highlighting the challenges and ways adopted to address them.
期刊介绍：
Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues.
Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
