“…Cycling performance of Li-Air cells with glyme electrolytes can be correctly evaluated only if a PLE is employed. Sulfolane (in combination with EA co-solvent and LiBF 4 salt) was chosen because of its exceptional oxidative stability [33].…”

The extremely high theoretical energy density of the lithium-oxygen couple makes it very attractive for nextgeneration battery development. However, there are a number of challenging technical hurdles that must be addressed for LiAir batteries to become a commercial reality. In this article, we demonstrate how the invention of water-stable, solid electrolyte-protected lithium electrodes solves many of these issues and paves the way for the development of aqueous and nonaqueous Li-Air batteries with unprecedented energy densities. We also show data for fully packaged Li-Air cells that achieve more than 800 Wh/kg.

“…Many novel solvents with a high anodic potential have been reported, including dinitriles, [177][178][179][180][181][182] sulfones, [183][184][185][186][187][188][189][190][191][192][193][194] and fluorinated solvents [195][196][197][198] . For example, in 1994, gluotaronitrile (GLN) and adioponitrile (ADN) were reported to offer exceptionally high anodic stability at ~8.3 V vs. Li + /Li.…”

Name., 2013, 00, 1-3 | 1 Electrolyte is a key component of electrochemical energy storage (EES) devices and its properties greatly affect the energy capacity, rate performance, cyclability and safety of all EES devices. This article offers a critical review of recent progresses and challenges in electrolyte research and development particularly for supercapacitors and supercapatteries, recharegable batteries (such as lithium-ion and sodium-ion batteries), and redox flow batteries (including fuel cells in a broad sense). The review will focus on liquid electrolytes, particularly aqueous and organic electrolytes, ionic liquids and molten salts. Influences of electrolyte properties on the performances of different EES devices are discussed in detail.

“…Electrolytes containing -butyrolactone (BL) or -valerolactone (VL) are very promising because these solvents have a large electrochemical window, a high flame point, a high boiling point, a low vapour pressure and a high conductivity at low temperatures in spite of a moderate permittivity and an absolute viscosity of 1.75 cP at 25°C. Sulfones such as ethylmethylsulfone (EMS), methoxy-methylsulfone (MEMS) or tetramethylsulfone (TMS) are good candidates for the high voltage electrolytes (electric vehicles) as their electrochemical stability in the presence of LiPF 6 remains good up to 5 V vs Li/Li + on platinum electrode [Watanabe et al, 2008;Sun & Angel, 2009;Abouimrane et al, 2009]. Unfortunately, these solvents cannot be used with graphite electrodes as they do not form a stable and protective SEI onto graphite.…”
