Nonnoble metal oxides for high‐performance Zn‐air batteries: Design strategies and future challenges

ZABs have made a solid contender for the next generation of electric transportation and electrical energy storage systems, thanks to their inherent high theoretical energy density. Nonetheless, the ZAB's most significant technological barrier to commercialization of ZABs is the air electrode's tardy oxygen reduction reaction and oxygen evolution reaction kinetics. Scientists have concentrated on perovskite-based catalysts due to the perovskite oxides' remarkable advantages. As the air electrode of ZABs is shown, the basic principles of ZABs and the attempt to raise the OER/ORR activity of perovskite oxides are shown.

Defective/Doped Graphene‐Based Materials as Cathodes for Metal–Air Batteries

MABs have been regarded as potential candidates for new-generation energy storage devices due to their extremely high theoretical energy density. Generally speaking, flawless graphene crystalline is inert for several catalytic reactions, although defects and heteroatoms can endow graphene with high activity for several electrocatalytic reactions. In aqueous or organic MABs, which are different electrochemical systems with specific requirements for air cathodes, latest development is summarized for deficient/doped graphene as air cathodes. Also, the connection between graphene defects/doping and electrocatalytic mechanisms that can be used to guide catalyst design is well established.
