1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3) belongs to benzothiophene derivatives. Benzothiophenes are valuable heterocycles that are widely used in medicines, agrochemicals, and materials science. It has been used as a raw material for the synthesis of biologically active structures and is found in pharmaceuticals such as leukotriene synthesis inhibitors and antifungals, as well as in many natural products.Formula: C2H4O4S

Ternary Electrolyte Additive Mixtures for Li-Ion Cells that Promote Long Lifetime and Less Reactivity with Charged Electrodes at Elevated Temperatures was written by Ma, Lin;Xia, Jian;Dahn, J. R.. And the article was included in Journal of the Electrochemical Society in 2015.Formula: C2H4O4S This article mentions the following:

Li[Ni1/3Mn1/3Co1/3]O2 (NMC111)/graphite and Li[Ni0.42Mn0.42Co0.16]O2 (NMC442)/graphite pouch cells demonstrate superb performance when ternary blends of electrolyte additives are added to the cells. These ternary blends contain one of vinylene carbonate (VC) or prop-1-ene-1,3-sultone (PES) plus a S containing mol. and tris(trimethylsilyl) phosphite (TTSPi). Here, the excellent charge-discharge capacity retention of cells containing these ternary blends of additives is demonstrated at both 45° and 55°C by comparison to cells with only VC or PES additives alone. The impact of a number of S- and phosphorous-containing electrolyte additives on the reactivity of charged electrode materials with electrolyte at elevated temperatures was studied using accelerating rate calorimetry (ARC). The electrolyte additives, methylene methanedisulfonate (MMDS) and TTSPi, dramatically reduce the reactivity between lithiated (charged) graphite and electrolyte. The ternary electrolyte blends of VC + MMDS + TTSPi and PES + MMDS + TTSPi show no reactivity between charged graphite and electrolyte to >200°. By contrast, electrolytes with no additives or with PES alone show significant reactivity with lithiated graphite <200°. NMC/graphite cells with VC + MMDS + TTSPi or PES + MMDS + TTPSi additives will demonstrate long life and excellent safety. In the experiment, the researchers used many compounds, for example, 1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3Formula: C2H4O4S).
