“…204,205 The latter has been known for their high anodic stability on cathodes but, simultaneously, poor ability to form effective SEI on graphitic anodes. 1 The integration of a sulfonyl isocyanate and a diisocyanate (Table 19, p-toluenesulfonyl iscyanate or PTSI, 3.4.1.5.…”

“…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.…”

“…However, their application in actual LIBs was limited by their inability to form a stable SEI layer on graphitic negatrodes. It has also been reported that the introduction of additives such as VC [186][187][188] , LiBOB, 189,190 p-toluenesulfonylisocyanate (PTSI) 191 and hexamethylenediisocyanate (HDI) 192 can promote SEI film formation in sulfone-based electrolytes, giving a cycling performance equal to the conventional carbonate electrolytes. Molecular dynamic simulations suggested that in the 1.0 mol L ─1 LiPF6/TMS+DMC electrolyte, TMS tended to preferentially adsorb on the positrode surface.…”

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.

“…Despite these interesting properties and studies focusing on cathodes performance [30,31], only few reports deal with carbon-based electrodes [32] and even less [33] with EC-free electrolytes able to operate a full Li-ion cell including graphite. Recently, Dahn's group reported on full Li-ion using VC and other additives in SL-based electrolytes [34] and we reported that, by use of carboxymethyl cellulose (CMC)/styrene-butadiene rubber (SBR)-based graphite anodes, efficient cycling of graphite is possible in a 1 M LiPF6 SL:DMC (1:1, wt.)…”

Abstract:Sulfolane (tetramethylene sulfone, SL) is known for leading to Li-ion electrolytes with high anodic stability. However, the operation of graphite electrodes in alternative electrolytes is usually challenging, especially when ethylene carbonate (EC) is not used as co-solvent. Thus, we study here the influence of the lithium salt on the physico-chemical and electrochemical properties of EC-free SL-based electrolytes and on the performance of graphite electrodes based on carboxymethyl cellulose (CMC). SL mixed with dimethyl carbonate (DMC) leads to electrolytes as conductive as state-of-theart alkyl carbonate-based electrolytes with wide electrochemical stability windows. The compatibility with graphite electrodes depends on the Li salt used and, even though cycling is possible with most salts, lithium difluoro-oxalato borate (LiDFOB) is especially interesting for graphite operation.LiDFOB electrolytes are conductive at room temperature (ca. 6 mS cm -1 ) with an anodic stability slightly below 5 V vs. Li/Li + on particulate carbon black electrodes. In addition, it allows cycling graphite electrodes with steady capacity and high coulombic efficiency without any additive. The testing of graphite electrodes in half-cells is, however, problematic with SL:DMC mixtures and, by switching the Li metal counter electrode for LiFePO4, the graphite electrode achieves better practical performance in terms of rate capability.
