Oxidative-stability enhancement and charge transport mechanism in glyme-lithium salt equimolar complexes.

TL;DR: The oxidative stability of glyme molecules is enhanced by the complex formation with alkali metal cations, resulting in the highest occupied molecular orbital (HOMO) energy level lowering of a glyme molecule, which is confirmed by ab initio molecular orbital calculations.
Journal ArticleDOI

Solvate Ionic Liquid Electrolyte for Li–S Batteries

TL;DR: In this paper, simple solvate ionic liquids, glyme-Li salt molten complexes, are presented as excellent electrolyte candidates because they greatly suppress the dissolution of lithium polysulfides, which leads to the stable operation of Li-S battery over more than 400 cycles with discharge capacities higher than 700 mAh g-sulfur−1 and with coulombic efficiencies higher than 98% throughout the cycles.
Journal ArticleDOI

Glyme-lithium salt equimolar molten mixtures: concentrated solutions or solvate ionic liquids?

TL;DR: In this article, the properties of equimolar mixtures of glymes (triglyme) and nine different lithium salts (LiX) were investigated and compared with the reported data on common aprotic ionic liquids.
Journal ArticleDOI

Ionic Liquid Electrolytes for Lithium–Sulfur Batteries

TL;DR: In this paper, a variety of binary mixtures of aprotic ionic liquids (ILs) and lithium salts were thoroughly studied as electrolytes for rechargeable lithium-sulfur (Li-S) batteries.

Glyme–Lithium Salt Equimolar Molten Mixtures: Concentrated Solutions or Solvate Ionic Liquids?

TL;DR: The lithium "solvate" ILs based on [Li(glyme)]X have many desirable properties for lithium-conducting electrolytes, including high ionicity, a high lithium transference number, high Li cation concentration, and high oxidative stability, in addition to the common properties of ionic liquids.
