Recently, a family of halogen-based Li-rich anti-perovskites was synthesized [J. Am. Chem. Soc. 134, 15042 (2012)], and the measured superionic conductivity makes these materials promising candidates as solid electrolytes for applications in Li-ion and Li-air batteries. This discovery raises several pressing issues on the fundamental physics concerning the thermodynamic and electrochemical stability of the synthesized materials and the mechanism of the observed superionic Li + transport. Here we study the reported anti-perovskites Li3OCl, Li3OBr and their mixed compounds using first-principles density functional theory and molecular dynamics simulations. Our calculations show that these materials are thermodynamically metastable. Their large electronic band gaps and chemical stability against electrodes suggest the excellent electrochemical performance, which bodes well for the use in potentially harsh working conditions in practical battery applications. The calculated low activation enthalpy for Li ion migration well below the crystal melting temperature and superionic transport near the Li sub-lattice melting state explain the experimentally observed phenomena. Our study identifies mobile Li vacancies and anion disorder as the primary driving mechanisms for superionic Li + conductivity in the anti-perovskites. The present work unveils essential working principles of the Li-rich anti-perovskites, which are crucial to further exploration, development, and application of these and other charge-inverted materials with tailored properties.

“…In virtue of the poor cell performance with solid polymer based electrolytes, non-polymer electrolytes provide a promising strategy for all-solid Li-S cells considering its inherent advantages of high thermal and chemical stability toward the Li anode under ambient atmosphere (Adachi et al, 1996;Robertson et al, 1997;Thangadurai and Weppner, 2006;Thangadurai et al, 2014). Since the first study on primary solid-state Li-ion batteries in 1972 (Scrosati, 1972), large number of inorganic solid-state electrolytes were investigated for Li-S cells as well as Li-ion batteries, including LiSICON-type phosphates, perovskite-type La (2/3)x Li 3x TiO 3 (LLT), Li 3 N, and Li 4 SiO 4 (Hayashi et al, 2003b;Stramare et al, 2003;Kobayashi et al, 2008;Nagao et al, 2011Nagao et al, , 2013.…”

With a theoretical specific energy five times higher than that of lithium-ion batteries (2,600 vs.~500Wh kg −1 ), lithium-sulfur (Li-S) batteries have been considered as one of the most promising energy storage systems for the electrification of vehicles. However, both the polysulfide shuttle effects of the sulfur cathode and dendrite formation of the lithium anode are still key limitations to practical use of traditional Li-S batteries. In this review, we focus on the recent developments in electrolyte systems. First, we start with a brief discussion on fundamentals of Li-S batteries and key challenges associated with traditional liquid cells. We then introduce the most recent progresses in liquid systems, including ether-based, carbonate-based, and ionic liquid-based electrolytes. And then we move on to the advances in solid systems, including polymer and non-polymer electrolytes. Finally, the opportunities and perspectives for future research in both the liquid and solid Li-S batteries are presented.

“…[70] The detail chemistry of organic (or inorganic) liquid electrolytes and solid state electrolytes as well as additives have been discussed in review articles [35,[71][72][73][74][75][76][77][78][79] and they refer to four major types of nonaqueous electrolytes such as organic liquids with Li salts, gel polymer electrolytes, solid electrolytes and ionic liquids. [72] Solid electrolytes have obvious advantages and disadvantages: they have excellent chemical and physical stability but low ionic conductivity, limited contact area with nanostructured electrode materials and suffer from interfacial stress due to volume changes of the electrodes during cycling.…”

“…[76] Inorganic glass (or ceramic) electrolytes such as perovskite-type, lithium nitrides and sulfides have also been considered as the solid electrolyte in all-solid-state Li ion cells. [77,78,80] Gel polymer electrolytes are intermediate between liquid and solids, and are composed of a polymer solid electrolyte and an organic liquid electrolyte (or ionic liquid). With this concept, two different types electrolytes could complement each other; for example, achieving better physical and chemical stability with good ionic conductivity.…”

Light metals have been widely used as electrode materials for batteries owing to their low standard redox potential, their low equivalent weight, large specific capacity, and great abundance. Both primary and secondary cells including light metals as electrode material have influenced all aspects of our lives, e.g., electrically operated toys, power tools, and portable electronics such as cell phones, smart pads, and laptop computers. Among all battery systems, rechargeable lithium (Li) ion cells have been used most widely in recent years owing to their high specific power, high energy density, and ambient temperature operation. However, Li‐ion cells are facing difficult challenges in satisfying the emerging market for advanced applications demanding high‐performance rechargeable batteries for applications such as electric vehicles, high‐performance portable electronics, and large‐scale electrical energy storage systems. Unfortunately, current Li‐ion cells cannot satisfy demands such as low cost, much improved safety, larger energy density, faster charge/discharge rates, and longer service life, so intensive effort is necessary to develop the next generation of cells. In this article, the limitations of current Li‐ion cells and various advanced materials for each component of the Li‐ion cell, in addition to other promising candidates for cells beyond Li ion, such as the Li/S cell and Na‐ and Mg‐based rechargeable cells, and metal/air cells are discussed.
