1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3) belongs to benzothiophene derivatives. Benzothiophene is relatively a stable molecule. The electrophilic substitution of benzothiophene systems is much less regioselective than that of indoles. The different substitution patterns in these heterocycles offer new opportunities for drug discovery and other applications in materials science.Formula: C2H4O4S

Optimizing electrolyte additive loadings in NMC532/graphite cells: vinylene carbonate and ethylene sulfate was written by Taskovic, T.;Thompson, L. M.;Eldesoky, A.;Lumsden, M. D.;Dahn, J. R.. And the article was included in Journal of the Electrochemical Society in 2021.Formula: C2H4O4S This article mentions the following:

A matrix of LiNi0.5Mn0.3Co0.2O2/graphite cells filled with 1.33 m LiPF6 in EC:EMC:DMC (ethylene carbonate: Et Me carbonate: di-Me carbonate) (25:5:70 by volume) electrolyte and different weight percentages of vinylene carbonate (VC) and ethylene sulfate (DTD) electrolyte additives underwent prolonged charge-discharge cycling at 20°C and 40°C. The volume of gas produced during formation and cycle testing was measured. The impedance spectra of the cells before and after cycling was measured. After testing, the electrolyte was extracted for study by NMR spectroscopy (NMR) and gas chromatog./mass spectroscopy (GC-MS) to determine what changes in electrolyte composition had occurred. Some cells had their neg. electrodes studied by scanning micro-X-ray fluorescence to quantify the amount of transition metals that transferred from the pos. electrode to the neg. electrode during the testing. Cells containing 1% VC or 2% VC with an addnl. 1% DTD by weight had the best capacity retention and lowest impedance growth. NMR and GC-MS suggest that these additive combinations promote increased electrolyte salt consumption which may represent a source of lithium to replenish the lithium inventory. Only a small amount of transition metals (0.03% or less) originating from the pos. electrode active material was found on the neg. electrode after testing. Most cells had over 1500 cycles at both 20°C and 40°C conditions. In the experiment, the researchers used many compounds, for example, 1,3,2-Dioxathiolane 2,2-dioxide (cas: 1072-53-3Formula: C2H4O4S).
