Nishioka, Kiho published the artcileN,N-Dimethylethanesulfonamide as an Electrolyte Solvent Stable for the Positive Electrode Reaction of Aprotic Li-O2 Batteries, Computed Properties of 143-24-8, the main research area is dimethylethanesulfonamide electrolyte solvent pos electrode lithium oxygen battery.
The realization of secondary lithium-oxygen batteries (Li-O2 batteries, LOBs) with large gravimetric energy d. requires the development of an innovative electrolyte with high chem. stability that allows the charge-discharge reaction to proceed with low overvoltage. In this study, we evaluated the potential of an electrolyte solvent, N,N-dimethylethanesulfonamide (DMESA) with a sulfonamide functional group, at a c.d. of 0.4 mA cm-2 and a capacity of 4 mA h cm-2. The voltage at which CO2 was generated during charging was substantially higher than that of a tetraglyme (G4)-based electrolyte with redox mediators, which is one of the standard electrolytes used for LOBs. Experiments using a 13C-containing pos. electrode revealed that CO2 generated during charging mainly originated from the decomposition of the pos. electrode. The analyses of the charging profile in conjunction with differential electrochem. mass spectrometry suggested the formation of highly degradable lithium peroxide (Li2O2) in the DMESA-based electrolyte. The formation of highly degradable Li2O2 enables a reduction of the charging voltage, leading to further suppression of the electrolyte decomposition
