“…The more upfield (more negative) 23 Na shifts recorded in the sulfamide-and sulfonamide-based electrolytes indicate weaker interactions between Na + and the solvation shell in these electrolytes. 29,30 Using the known DNs of DMSO (29.8 kcal/mol 31 ), DMF (26.6 kcal/mol 31 ), DME (20.2 kcal/mol 30 ), and PC (15.1 kcal/mol 32 ) and their 23 Na NMR shifts, 33 we estimated the DNs of BTMSA, DMCF 3 SA, and BMCF 3 SA to be 16.9, 16.4, and 13.3 kcal/mol, respectively (Figure 2B). The low DNs of these three solvents suggest that they will have lower superoxide solubility 24,26 and thus higher chemical stability than high-DN solvents such as DMSO and DMF.…”

Aprotic lithium-oxygen (Li-O 2 ) batteries show great promise in energy storage and transportation applications because of their high gravimetric energies, which potentially represent a several-fold increase over Li-ion batteries. The stable and reversible operation of Li-O 2 batteries, however, is currently hindered by the severe degradation of common electrolytes. Here, we show that sulfonamidebased electrolytes, designed on the basis of physical organic chemistry principles, can exhibit higher (electro)chemical stability than common electrolytes, such as tetraglyme and DMSO.
