In 2019,Journal of the Electrochemical Society included an article by Gauthier, Roby; Hall, David S.; Taskovic, T.; Dahn, J. R.. Product Details of 872-36-6. The article was titled 《A joint DFT and experimental study of an imidazolidinone additive in lithium-ion cells》. The information in the text is summarized as follows:
Electrolyte additives are a practical route to improving the lifetime and performance of lithium-ion cells. It is not well understood what makes a good additive; thus, the discovery of new additives poses a significant challenge. Computational methods have the potential to streamline the search for new additives, but it is important to compare predicted additive behavior with exptl. measured results. A new electrolyte additive, 1,3-dimethyl-2-imidazolidinone (DMI), has been evaluated in LiNi1-x-yMnxCoyO2 (NMC)/graphite pouch cells as a single additive and with the co-additive vinylene carbonate (VC). This work compares the d. functional theory (DFT)-predicted behavior of DMI with exptl. results, including differential capacity anal. (dQ/dV), electrochem. impedance spectroscopy (EIS), high-temperature storage, gas chromatog.-mass spectrometry (GC-MS) and long-term cycling tests. The DFT-calculated reduction potential of DMI is -0.63 V vs Li/Li+, consistent with the exptl. observation that it reduces at a lower potential than ethylene carbonate (EC), ∼0.80 V vs Li/Li+. Although DMI turns out not to be a competitively useful additive, the good match between many aspects of the exptl. results and theor. predictions is a good indication that it is possible to understand aspects of the behavior of additives. This can guide future researchers. In addition to this study using Vinylene carbonate, there are many other studies that have used Vinylene carbonate(cas: 872-36-6Product Details of 872-36-6) 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.Product Details of 872-36-6
