“…Due to the development of new energy industry, the high demand for Li resources has promoted the rapid rise of Li prices. At this rate, Li could run out in the next 20 years 178 . Thus, some metal resources with high content and low cost have become an inevitable trend in battery research (NABs and KABs).…”

With the rapid development of wearable and intelligent flexible electronic devices (FEDs), the demand for flexible energy storage/conversion devices (ESCDs) has also increased. Rechargeable flexible metal‐air batteries (MABs) are expected to be one of the most ideal ESCDs due to their high theoretical energy density, cost advantage, and strong deformation adaptability. With the improvement of the device design, material assemblies, and manufacturing technology, the research on the electrochemical performance of flexible MABs has made significant progress. However, achieving the high mechanical flexibility, high safety, and wearable comfortability required by FEDs while maintaining the high performance of flexible MABs are still a daunting challenge. In this review, flexible Zn‐air and Li‐air batteries are mainly exemplified to describe the most recent progress and challenges of flexible MABs. We start with an overview of the structure and configuration of the flexible MABs and discuss their impact on battery performance and function. Then it focuses on the research progress of flexible metal anodes, gel polymer electrolytes, and air cathodes. Finally, the main challenges and future research perspectives involving flexible MABs for FEDs are proposed.

“…Regarding the carbon-centered radical species that were detected in the absence of Li2O2 (see Figure (2A)), the generation of these species would be associated with a auto-oxidation phenomenon, common in this type of solvents [1,[29][30][31].…”

“…Lithium-air batteries stand out for their high density compared to the existing lithium-ion battery technology. Despite their promising future, these systems are still in a research stage, due to their limited cyclability as a result of parasitic reactions that occur between the cathode and the electrolyte during the successive charging and discharging processes [1]. These products come more specifically from decomposition of solvent [2], electrolyte [3,4], the carbon [5] and the binder [6].…”

In this work, the decomposition of the solvent tetraethylene glycol dimethyl ether (TEGDME) was studied under conditions that simulate the charge of a Li-O2 cell in the presence and absence of hydrogen peroxide and lithium peroxide by means of electron spin resonance spectroscopy (ESR). We detected the formation of radical species, although in low concentrations, originating from solvent decomposition reactions during the oxidation process, in the absence of peroxides. On the other hand, by introducing H2O2 and H2O into the system, oxygen-centered superoxide and hydroxyl radical species were detected. Furthermore, in the presence of Li-O2, carbon-centered radical species were detected which clearly show the decomposition of the solvent. Finally, the results show that it is very important that the charging process of a Li-O2 cell is carried out by direct oxidation via 2 eto Li2O2 to avoid the formation of radical species that the decomposition of the solvent.

“…Lithium–oxygen batteries (LOBs) have recently emerged as a promising alternative for large‐scale energy storage applications due to their high theoretical energy density (≈3500 Wh kg –1 ) and low cost. [ 1 ] However, the sluggish kinetics of the oxygen reduction reaction (ORR) and oxygen evolution reaction (OER), which are firmly related to the formation and decomposition of Li 2 O 2 at the cathode, have caused significant polarization and poor cyclability in LOBs. [ 1c,2 ] Thus, a bifunctional electrocatalyst with high activity and stability is required to address these issues in the LOB cathode.…”

Oxygen electrolysis is the key component of lithium–oxygen batteries, which require highly active cathode catalysts to reduce cathode polarization and improve cycling stability, while metal–organic frameworks (MOFs) and MOF‐derived carbon‐based materials have aroused great interest as alternatives to noble‐metal oxygen electrocatalysts. Herein, a single‐walled metal–organic nanotube (MONT), Ni(II)(C6H7NO6)(H2O), with a novel crystal structure, is synthesized and doped with cobalt to be used as precursors to produce the uniformly distributed high‐density NiCo alloy nanoparticles, which are encapsulated by the graphitized N‐doped carbon (NiCo@NC) and supported on the nanorods based on the structural and morphological characteristics of the MONT precursor. Benefited from the uniformly distributed high‐density catalytic active sites, bimetal alloy composition, and excellent mass transfer structure, the as‐derived NiCo@NC catalyst endows the assembled lithium–oxygen battery with a low overpotential of 0.98 V, a high discharge capacity of 12 477 mAh g–1, and more importantly, the excellent cycling stability of over 800 h. These findings demonstrate the potential of this superb catalyst in high‐performance lithium–oxygen batteries and diverse energy conversion and storage devices.
