“…Amici et al proposed an OSM by attaching silicone oil onto poly(vinylidene fluoride co‐hexafluoropropylene) (PVdF‐HFP) with high hydrophobicity. [ 107 ] The discharge–charge profiles with and without OSM show similar behavior at the first cycle of the Li–air battery, both with a Coulombic efficiency of 88% (Figure 3b). However, a noticeable difference starts to appear at open‐circuit voltage (OCV) after 10 days.…”

Over the past few years, great attention has been given to nonaqueous lithium-air batteries owing to their ultrahigh theoretical energy density when compared with other energy storage systems. Most of the research interest, however, is dedicated to batteries operating in pure or dry oxygen atmospheres, while Li-air batteries that operate in ambient air still face big challenges. The biggest challenges are H2O and CO2 that exist in ambient air, which can not only form byproducts with discharge products (Li2O2), but also react with the electrolyte and the Li anode. To this end, recent progress in understanding the chemical and electrochemical reactions of Li-air batteries in ambient air is critical for the development and application of true Li-air batteries. Oxygen-selective membranes, multifunctional catalysts, and electrolyte alternatives for ambient air operational Li-air batteries are presented and discussed comprehensively. In addition, sepa-rator modification and Li anode protection are covered. Furthermore, the challenges and directions for the future development of Li-air batteries are presented

“…Most current studies of Li−O 2 batteries have been performed in pure O 2 atmosphere to rule out any harmful effects on the battery performance from moisture, nitrogen, or carbon dioxide . The employment of an O 2 ‐selective membrane has proven to be a promising approach for achieving the ultimate goal of real “Li−air” batteries that use air rather than pure O 2 . Considering their high surface area, tailorable pore size, and functional sites, MOFs have exhibited great potential for application in gas separation such as CO 2 capture from combustion gases …”

frameworks (MOFs) are a relatively new class of crystalline, highly-porous organic-inorganic hybrid materials that have been attracting increasing attention in the field of high-energy lithium batteries. In this review, recent achievements are detailed regarding the innovative design and processing of pristine MOFs and their nanocomposites for lithiumÀsulfur and lithiumÀoxygen batteries with high specific energy. Furthermore, the benefits and challenges associated with the applications of MOF-based materials in solid-state lithium-metal batteries are discussed. Lastly, future prospects for the rational design and manufacturing of MOF-based materials are provided.can also be used as Li-ion conductors for all-solid-state electrolytes, wherein Li + ions can be fast mobilized along open metal sites. [12d,16] There are several good review articles addressing MOFderived materials (e. g., porous carbon or metal oxides) for energy storage applications, [10,17] which are not covered in detail in this review. Here, a comprehensive overview is provided that focuses on recent advancement in pristine MOFs and their nanocomposites for emerging high-energy Li batteries (LiÀS, LiÀO 2 , and solid-state Li-metal batteries). Furthermore, the advantages and challenges associated with the development of MOF-based materials are discussed. Lastly, the future prospects for the rational design and manufacturing of MOF-based materials are outlined. 2 3 4 5 6 7 8

“…On the other hand, Jung et al incorporated Pyr14 TFSI in a PVDF–HFP-based GPE [379] and observed that PVDF–HFP undergoes extensive elimination reactions upon exposure to peroxide, which was also confirmed by Amanchukwu et al [371]. However, with a PVDF HFP-based membrane, few signs of deterioration were detected over 16 cycles in a Li-air cell [380]. Some researchers claim the merits of PVDF–HFP, considering that its use is promising [381].…”

Most of the current commercialized lithium batteries employ liquid electrolytes, despite their vulnerability to battery fire hazards, because they avoid the formation of dendrites on the anode side, which is commonly encountered in solid-state batteries. In a review two years ago, we focused on the challenges and issues facing lithium metal for solid-state rechargeable batteries, pointed to the progress made in addressing this drawback, and concluded that a situation could be envisioned where solid-state batteries would again win over liquid batteries for different applications in the near future. However, an additional drawback of solid-state batteries is the lower ionic conductivity of the electrolyte. Therefore, extensive research efforts have been invested in the last few years to overcome this problem, the reward of which has been significant progress. It is the purpose of this review to report these recent works and the state of the art on solid electrolytes. In addition to solid electrolytes stricto sensu, there are other electrolytes that are mainly solids, but with some added liquid. In some cases, the amount of liquid added is only on the microliter scale; the addition of liquid is aimed at only improving the contact between a solid-state electrolyte and an electrode, for instance. In some other cases, the amount of liquid is larger, as in the case of gel polymers. It is also an acceptable solution if the amount of liquid is small enough to maintain the safety of the cell; such cases are also considered in this review. Different chemistries are examined, including not only Li-air, Li–O2, and Li–S, but also sodium-ion batteries, which are also subject to intensive research. The challenges toward commercialization are also considered.
