The room‐temperature molten salt mixture of N,N‐diethyl‐N‐(2‐methoxyethyl)‐N‐methylammonium bis(trifluoromethanesulfonyl) imide ([DEME][TFSI]) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) salt is herein reported as electrolyte for application in Li–O2 batteries. The [DEME][TFSI]–LiTFSI solution is studied in terms of ionic conductivity, viscosity, electrochemical stability, and compatibility with lithium metal at 30 °C, 40 °C, and 60 °C. The electrolyte shows suitable properties for application in Li–O2 battery, allowing a reversible, low‐polarization discharge–charge performance with a capacity of about 13 Ah g0pt-12.84526ptcarbon2.84526pt in the positive electrode and coulombic efficiency approaching 100 %. The reversibility of the oxygen reduction reaction (ORR)/oxygen evolution reaction (OER) is demonstrated by ex situ XRD and SEM studies. Furthermore, the study of the cycling behavior of the Li–O2 cell using the [DEME][TFSI]‐LiTFSI electrolyte at increasing temperatures (from 30 to 60 °C) evidences enhanced energy efficiency together with morphology changes of the deposited species at the working electrode. In addition, the use of carbon‐coated Zn0.9Fe0.1O (TMO‐C) lithium‐conversion anode in an ionic‐liquid‐based Li‐ion/oxygen configuration is preliminarily demonstrated.

“…[ 3,20,70–73 ] Although Hamid and co‐workers specifically summarized how the membrane technology can mitigate crucial challenges associated with air cathodes, lithium metal anodes, and electrolytes, a detailed review on the progress on making Li–air batteries truly work in ambient air atmosphere is still lacking. [ 74 ] In this review, we particularly focus on the development of Li–air batteries operating in ambient air to facilitate further advances on true Li–air batteries toward their original intention. Figure provides an overview of the strategies reported in recent years to operate ambient nonaqueous Li–air batteries.…”

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

“…To enhance the energy density (and to reduce the specific weight) of batteries, one of the most cited approaches is the metal-air battery technology, which includes the idea of allowing the metal ions to react with oxygen on the surface of the electrode, thus making the capacity of the battery depend on the surface area of the electrode instead of its volume. Lithium-air technology, for example, allows the theoretical energy density of more than 2…3 kWh/kg (0.3…0.5 kg/kWh), which is several times better than the energy density of the best lithium-ion batteries: 0.25 kWh/kg (4 kg/kWh) [127]. It has been also demonstrated that the use of a graphene-silica assembly (graphene ball) as an anode material would elevate the energy density of a lithium-ion battery to 800 Wh/L, which is more than twice as much as in the state-of-the-art topologies [128].…”

The continuous and rapid development of energy technology challenges the scientific community to ponder the long-term energy evolution from the perspective of sustainable energy transition.We state that one of the key challenges for the new (post-fossil) energy era is to guarantee to all energy users an access to adequate resources of energy everywhere and at any moment of time.To crystallize the key ideas of such a pervasive energy supply chain into a single concept, we introduce the concept 'ubiquitous energy'. The main contribution of our paper is to create a discussion framework for the concept and to identify the most relevant technology pathways for the realization of 'ubiquitous energy'. Hence, we first present the background of the concept and discuss matters concerning the 'quality of energy to be present everywhere'. Secondly, we review the latest innovations in energy technology with respect to the energy supply chain and summarize technology pathways to 'ubiquitous energy'. To that end, we describe a systematic framework to classify energy technologies under energy generation, storage, transmission and distribution. We conclude that 'ubiquitous energy' covers various solutions in both scope and degree of integration, but the most prominent trend of development is the use of distributed and shared resources and local energy supply chains. Here, the research should focus on integrated and mobile energy conversion and storage options and wireless power transmission.
