“…Aqueous metal-air batteries with high theoretical energy densities, based on zinc (Zn), aluminum (Al), magnesium (Mg), and iron (Fe), have attracted renewed interest as a promising energy storage candidate for mobile and electronic devices, benefiting from the advantages of low cost, abundant raw materials, environmental friendliness, and operational safety. 10 The aqueous metal-air batteries adopt a half-open configuration that can utilize oxygen as a reactant from the ambient atmosphere and as such achieve a high energy density. Typically, an aqueous metal-air battery consists of a metal electrode, an alkaline electrolyte, and an air electrode which is comprised of a catalyst layer, a current collector, and a gas diffusion layer (GDL).…”

The exploration of aqueous flexible metal–air batteries with high energy density and durability has attracted many research efforts with the demand for portable and wearable electronic devices. Aqueous flexible metal–air batteries feature Earth‐abundant materials, environmental friendliness, and operational safety. Each part of one metal–air battery can significantly affect the overall performance. This review starts with the fundamental working principles and the basic battery configurations and then highlights on the common issues and the recent advances in designing high‐performance metal electrodes, solid‐state electrolytes, and air electrodes. Bifunctional oxygen electrocatalysts with high activity and long‐term stability for constructing efficient air electrodes in flexible metal–air batteries are summarized including metal‐free carbon‐based materials and nonprecious Co/Fe‐based materials (alloys, metal oxides, metal sulfites, metal phosphates, metal nitrates, single‐site metal–nitrogen–carbon materials, and composites). Finally, a perspective is provided on the existing challenges and possible future research directions in optimizing the performance and lifetime of the flexible aqueous solid‐state metal–air batteries.

“…As described in Figure c, the discharge products at the cathode in metal–air batteries are metal oxides represented by MO 2 x . Consequently, the efficiency of converting oxygen gas molecules from air to O 2– anions and generating MO 2 x with metal cations from the metal anode governs the overall rate of a discharge reaction and its subsequent voltage . Inversely, the discharge product, MO 2 x , should be rapidly decomposed into metal and oxygen gas at the cathode during charging.…”

As chemical reactions and charge-transfer simultaneously occur on the catalyst surface during electrocatalysis, numerous studies have been carried out to attain an in-depth understanding on the correlation among the surface structure and composition, the electrical transport, and the overall catalytic activity. Compared with other catalysis reactions, a relatively larger activation barrier for oxygen evolution/reduction reactions (OER/ORR), where multiple electron transfers are involved, is noted. Many works over the past decade thus have been focused on the atomic-scale control of the surface structure and the precise identification of surface composition change in catalyst materials to achieve better conversion efficiency. In particular, recent advances in various analytical tools have enabled noteworthy findings of unexpected catalytic features at atomic resolution, providing significant insights toward reducing the activation barriers and subsequently improving the catalytic performance. In addition to summarizing important surface issues, including lattice defects, related to the OER and ORR in this Review, we present the current status and discuss future perspectives of oxide- and alloy-based catalysts in terms of atomic-scale observation and manipulation.
