“…Its energy density (4346 Wh kg −1 ) was also higher than other metal-air battery with commercial Ag powders as catalyst. [47] It is well known that non-noble metal catalysts have many advantages, such as comparable activities and low-cost. As reported, Fe/N codoped carbon catalysts have been considered as the potential candidates for primary Zn-O 2 [48] and Al-O 2 batteries.…”

New types of electrochemical energy conversion and storage devices based on redox electrocatalytic reactions possess great potential in renewable energy to maximize energy utilization and balance environmental issues. The typical device is the metal‐redox bicatalysis battery, where the cathode is redox bifunctional catalyst (named as redox bicatalyst) with gas, solid, liquid as active reactants while anode is metal, driven by cathodic redox electrocatalytic reactions during charge/discharge processes, which promotes the energy storage and chemical production. In this system, the metal anode, redox‐bicatalyst cathode, electrolytes, and the redox electrochemical reactions can be modified and adjusted to achieve the optimal energy conversion and utilization. Therefore, the deep understanding of the electrochemical system is conducive to designing new devices to meet the demand among various applications, including energy storage and conversion. In this review, the authors clarify the fundamentals and design principles of the rechargeable/reversible metal‐redox bicatalysis batteries and how each part affects the devices in energy conversion and chemical production. The authors summarize the electrocatalytic reduction/oxidation reactions, the reported systems relied on redox reactions, and the corresponding redox bicatalysts. Finally, a perspective of the key challenges and the possible new types of metal‐redox bicatalysis batteries for efficient energy utilization and chemical production are given.

“…Additionally, the open-circuit voltage was preserved by roughly 98 % following 1000 cycles of bending in a gel electrolyte. [66] Lu and coworkers [77] also reported the self-reduction synthesis of Agcarbon fibre paper (AgÀ CFP) as an air electrode of AAB. Functional groups on the carbon surface (substrate) in-situ reduced the Ag precursor, resulting in 100 nm AgNPs.…”

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

“…For example, various Ag nanostructures have been loaded onto different carbon substrates to form Ag/carbon composites for efficient ORR catalysis at an acceptable low‐cost for primary metal–O 2 batteries, including Zn–O 2 , Mg–O 2 , and Al–O 2 batteries . Remarkably, an Al–O 2 battery using such a Ag/carbon composite (Ag NPs on carbon fiber paper, Ag‐CFP) as the catalytic air cathode exhibited a very high power density (108.1 mW cm −2 ), capacity (2917 mAh g −1 ), and energy density (4346 Wh kg −1 ), which are much better than the performance of the air electrode by directly using commercial Ag powders (Figure c,d) …”

The success of Li–air/O2 batteries has brought extensive attention to the development of various promising non‐Li metal–O2 batteries, such as Zn–O2, Al–O2, Mg–O2 batteries, etc., which have exhibited unique advantages, such as low production cost, high energy density, and much enhanced safety. The versatile non‐Li metal–O2 batteries provide a better opportunity for meeting the practical requirements for sustainable energy supplies in various applications. A high‐performance cathode in non‐Li metal–O2 batteries that can effectively trigger both oxygen reduction and evolution reactions and thus boost the overall battery performance is of great research interest. In this article, a comprehensive review on the development of Li‐free metal–O2 batteries and particularly focusing on the oxygen catalytic cathodes for both primary and secondary non‐Li metal–O2 batteries is carefully performed. The current challenges and potential solutions are also outlined and proposed. Through carefully selecting and rationally designing promising catalytic cathodes, a series of non‐Li metal–oxygen batteries toward practical energy storage applications are highly anticipated.
