“…While the results are promising, the researchers cautioned that a practical lithium-air battery is unlikely to be available for at least a decade. More recently, a new variation of the lithium-air battery, the nanolithia cathode, was reported that could be used in a conventional, fully sealed battery [50]. The team expects to move from this laboratory-based proof of concept to a practical prototype within a year.…”

We present the results of our eighth annual horizon scan of emerging issues likely to affect global biological diversity, the environment, and conservation efforts in the future. The potential effects of these novel issues might not yet be fully recognized or understood by the global conservation community, and the issues can be regarded as both opportunities and risks. A diverse international team with collective expertise in horizon scanning, science communication, and conservation research, practice, and policy reviewed 100 potential issues and identified 15 that qualified as emerging, with potential substantial global effects. These issues include new developments in energy storage and fuel production, sand extraction, potential solutions to combat coral bleaching and invasive marine species, and blockchain technology. Aims of Horizon ScanningWe have conducted an annual horizon scan of global conservation issues since 2010 with the aim of highlighting, by consensus, emerging topics that are not yet widely known in the conservation community but could have substantial effects on biological diversity worldwide in the medium to long term. Our iterative, transferable process of horizon scanning, which is designed to be both transparent and democratic, is carried out by a team with a wide range of experiences and areas of expertise.Our aim has been to focus attention and stimulate debate about these subjects, potentially leading to new research foci, policy developments, or business innovations. These responses should help to facilitate better-informed forward-planning. It is difficult to gauge the direct effects of our horizon scans on the research, policy, or business communities, except through personal communication and hearsay. However, several topics recognized in our previous horizon scans Trends This is the eighth such annual horizon scan.An international team with expertise in horizon scanning, science communication, and conservation research, practice, and policy identified 15 issues, following widespread consultation and a Delphi-like scoring process to identify the most important.The issues were wide ranging, and include sand extraction, blockchain technology, use of robotics to combat invasive species, and new developments in energy storage and fuel production. There is now substantial action on this issue internationally, with several governments, including those of the USA and the UK, introducing legislative bans on microbeads in cosmetics and detergents, and many cosmetics companies voluntarily committing to halt their use of microplastics by 2020 [2,3]. New research on the effects of microbeads has revealed biological responses in both terrestrial and aquatic environments, with evidence demonstrating that microplastics reduce the survival and fitness of earthworms Lumbricus terrestris [4] and facilitate the accumulation of sorbed organic pollutants in fish [5]. Discussion of the use of gene editing to control invasive species or disease vectors, raised in our 2014 horizon scan [6], has increased...

“…With ever increasing demand for high-performance lithium-ion batteries, cathode materials with high energy density have been sought from diverse chemical spaces 1–3 . Recently, Li-excess disordered (rocksalt) transition metal oxides (LEX-RS), such as Li 1.211 Mo 0.467 Cr 0.3 O 2 , Li 1.3 Mn 0.4 Nb 0.3 O 2 , Li 1.2 Mn 0.4 Ti 0.4 O 2 , and Li 1.2 Ni 0.333 Ti 0.333 Mo 0.133 O 2 , have gained much attention as a new class of high-capacity cathode materials, delivering capacities as high as 300 mAh g –1 4–12 .…”

Mitigating oxygen loss to improve the cycling performance of high capacity cation-disordered cathode materials

et al. 2017

Recent progress in the understanding of percolation theory points to cation-disordered lithium-excess transition metal oxides as high-capacity lithium-ion cathode materials. Nevertheless, the oxygen redox processes required for these materials to deliver high capacity can trigger oxygen loss, which leads to the formation of resistive surface layers on the cathode particles. We demonstrate here that, somewhat surprisingly, fluorine can be incorporated into the bulk of disordered lithium nickel titanium molybdenum oxides using a standard solid-state method to increase the nickel content, and that this compositional modification is very effective in reducing oxygen loss, improving energy density, average voltage, and rate performance. We argue that the valence reduction on the anion site, offered by fluorine incorporation, opens up significant opportunities for the design of high-capacity cation-disordered cathode materials.

Alkali metal–O2 batteries, by coupling high‐capacity alkali metal anodes with gaseous oxygen, possess extremely high gravimetric energy density that is comparable to gasoline and are potential energy storage technologies beyond lithium–ion batteries. The development of alkali metal–O2 batteries has achieved great progress in recent years, from materials to prototype devices and on fundamental mechanisms. The stability of alkali metal–O2 batteries is still poor, however, leading to a huge gap between laboratory research and commercial applications. A series of parasitic reactions result in the instability, which occur during electrochemical discharging and charging. The ubiquitous active oxygen species attack both the organic electrolyte and the carbon cathode, triggering various parasitic reactions. Meanwhile, dendrite growth and volume expansion upon repeated plating/stripping and O2 crossover severely limit the reversibility of alkali metal anodes. Here, an overview of the strategies against these issues is given to improve the stability of nonaqueous alkali metal–O2 batteries, which is discussed from three aspects: air cathodes, alkali metal anodes, and aprotic electrolytes. Furthermore, perspectives for future research of stable alkali metal–O2 batteries are outlined.
