In 2019,Journal of the Electrochemical Society included an article by Schwenke, K. Uta; Solchenbach, Sophie; Demeaux, Julien; Lucht, Brett L.; Gasteiger, Hubert A.. Synthetic Route of C3H2O3. The article was titled 《The impact of CO2 evolved from VC and FEC during formation of graphite anodes in lithium-ion batteries》. The information in the text is summarized as follows:
Additives such as vinylene carbonate (VC) and fluoroethylene carbonate (FEC) are commonly added to Li-ion battery electrolytes in order to form a solid electrolyte interphase (SEI) on the anode, suppressing continuous solvent reduction Here, we directly compare VC and FEC by analyzing the SEI with FTIR and XPS, and the evolved gases with online electrochem. mass spectrometry (OEMS) in different model systems. Since both additives evolve mainly CO2 during formation, the effect of CO2 as an additive is compared to the addition of VC and FEC. While Li2CO3 is as expected the main SEI compound found due to the added CO2, surprisingly no CO was detected in the gas phase of such cells. Based on FTIR, NMR and OEMS analyses of cells filled with 13C labeled CO2, we suggest a mechanism explaining the beneficial effects of CO2 and hence also of CO2 evolving additives in lithium-ion battery cells. While the generation of polycarbonate from FEC or VC reduction is observed, the generation of Li2CO3 may be as important as the generation of polycarbonate. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Synthetic Route of C3H2O3) was used in this study.
Vinylene carbonate(cas: 872-36-6) belongs to esters. Alkyl carbonates find applications as solvents for lithium ion battery electrolytes and the use of high quality battery grade electrolytes having extremely low water (<10 ppm) and acid (<10 ppm) contents are critical for achieving high electrochemical performance.Synthetic Route of C3H2O3
