Lithium–air (Li–air) batteries stand out among the post‐Li‐ion batteries due to their high energy density, which has rapidly progressed in the past years. Regarding the fundamental mechanism of Li–air batteries that discharge products produced and decomposed during charging and recharging progress, the reversibility of products closely affects the battery performance. Along with the upsurge of the mainstream discharge products lithium peroxide, with devoted efforts to screening electrolytes, constructing high‐efficiency cathodes, and optimizing anodes, much progress is made in the fundamental understanding and performance. However, the limited advancement is insufficient. In this case, the investigations of other discharge products, including lithium hydroxide, lithium superoxide, lithium oxide, and lithium carbonate, emerge and bring breakthroughs for the Li–air battery technologies. To deepen the understanding of the electrochemical reactions and conversions of discharge products in the battery, recent advances in the various discharge products, mainly focusing on the growth and decomposition mechanisms and the determining factors are systematically reviewed. The perspectives for Li–air batteries on the fundamental development of discharge products and future applications are also provided.

“…The effect of the Li salt nature and concentration on the operation of the Li–O 2 cell has been investigated by several studies, reporting promising results for cells using lithium trifluoromethanesulfonate (LiCF 3 SO 3 ) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in glyme-based electrolytes characterized by high Li + transference number and ionic conductivity, e.g., with tetraethylene glycol dimethyl ether (TEGDME) as the solvent. ,, Despite the role of the Li + diffusion to the electrode–electrolyte interphase on the cell performances has been widely investigated for Li-ion − and Li–S batteries, , only a limited deal of studies correlated the kinetics of Li + diffusion to the performances of Li–O 2 batteries . Efficient ORR/OER processes have been suggested for Li–O 2 cells using GDLs, for facilitating the diffusion of involved species, with various substrates which promote the reaction kinetics, e.g., nanosized carbon, ,, metals, − metal oxides, − and conductive polymers . Based on these premises, herein we reported a detailed study of various commercially available GDLs used as the support for the cathode material.…”

Lithium−oxygen (Li−O 2 ) batteries are nowadays among the most appealing next-generation energy storage systems in view of a high theoretical capacity and the use of transitionmetal-free cathodes. Nevertheless, the practical application of these batteries is still hindered by limited understanding of the relationships between cell components and performances. In this work, we investigate a Li−O 2 battery by originally screening different gas diffusion layers (GDLs) characterized by low specific surface area (<40 m 2 g −1 ) with relatively large pores (absence of micropores), graphitic character, and the presence of a fraction of the hydrophobic PTFE polymer on their surface (<20 wt %). The electrochemical characterization of Li−O 2 cells using bare GDLs as the support indicates that the oxygen reduction reaction (ORR) occurs at potentials below 2.8 V vs Li + /Li, while the oxygen evolution reaction (OER) takes place at potentials higher than 3.6 V vs Li + /Li. Furthermore, the relatively high impedance of the Li−O 2 cells at the pristine state remarkably decreases upon electrochemical activation achieved by voltammetry. The Li−O 2 cells deliver high reversible capacities, ranging from ∼6 to ∼8 mA h cm −2 (referred to the geometric area of the GDLs). The Li−O 2 battery performances are rationalized by the investigation of a practical Li + diffusion coefficient (D) within the cell configuration adopted herein. The study reveals that D is higher during ORR than during OER, with values depending on the characteristics of the GDL and on the cell state of charge. Overall, D values range from ∼10 −10 to ∼10 −8 cm 2 s −1 during the ORR and ∼10 −17 to ∼10 −11 cm 2 s −1 during the OER. The most performing GDL is used as the support for the deposition of a substrate formed by few-layer graphene and multiwalled carbon nanotubes to improve the reaction in a Li−O 2 cell operating with a maximum specific capacity of 1250 mA h g −1 (1 mA h cm −2 ) at a current density of 0.33 mA cm −2 . XPS on the electrode tested in our Li−O 2 cell setup suggests the formation of a stable solid electrolyte interphase at the surface which extends the cycle life.

“…In the past decade, a number of excellent books and review articles have been published regarding non-aqueous or aqueous Li–air batteries ( Feng et al, 2016 ; Kwak et al, 2020 ; Dou et al, 2022 ; Liu et al, 2022 ), but the latest article for the aqueous Li–air battery has been published for more than 3 years, best to our knowledge ( Imanishi and Yamamoto, 2019 ). As significant approaches have been made day by day, it is necessary to summarize and review them in order to accelerate the research pace for the application of aqueous Li–air batteries.…”

The lithium–air (Li–air) battery utilizes infinite oxygen in the air to store or release energy through a semi-open cathode structure and bears an ultra-high theoretical energy density of more than 1,000 Wh/kg. Therefore, it has been denoted as the candidate for next-generation energy storage in versatile fields such as electric vehicles, telecommunications, and special power supply. Among all types of Li–air batteries, an aqueous Li–air battery bears the advantages of a high theoretical energy density of more than 1,700 Wh/kg and does not have the critical pure oxygen atmosphere issues in a non-aqueous lithium–air battery system, which is more promising for the actual application. To date, great achievements have been made in materials’ design and cell configurations, but critical challenges still remain in the field of the solid electrolyte separator, its related lithium stripping/plating at the lithium anode, and catholyte design. In this mini-review, we summarized recent progress related to the solid electrolyte in aqueous Li–air batteries focusing on both material and battery device development. Moreover, we proposed a discussion and unique outlook on improving solid electrolyte compatibility and battery performance, thus designing an aqueous Li–air battery with higher energy density and better cycle performance in the future.
