New electrolytes with large electrochem. windows are needed to meet the challenge for high-voltage Li-ion batteries. Sulfone as an electrolyte solvent boasts of high oxidation potentials. Here we examine the effect of multiple functionalization on sulfone oxidation potential. We compute oxidation potentials for a series of sulfone-based mols. functionalized with fluorine, cyano, ester, and carbonate groups by using a quantum chem. method within a continuum solvation model. We find that multifunctionalization is a key to achieving high oxidation potentials. This can be realized through either a fluoroether group on a sulfone mol. or sulfonyl fluoride with a cyano or ester group. In the experiment, the researchers used many compounds, for example, Methyl 2-(methylsulfonyl)acetate (cas: 62020-09-1Product Details of 62020-09-1).
Methyl 2-(methylsulfonyl)acetate (cas: 62020-09-1) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Product Details of 62020-09-1
