NEW IONICALLY CONDUCTIVE MATERIAL WITH IMPROVED CONDUCTIVITY AND STABILITY

摘要

Sulfamides or mixtures thereof having the formulaR1 R2 NSO2 N R3 R4wherein one to three R substituents are methyl groups, the remainderbeing ethyl groups, or one R is a methoxyethyl, the remaining R beingmethyl or ethyl groups. They are useful as electrolytic composition withoutstanding conductivity and aprotic solvents. An electrolytecomprising them is highly useful in a lithium battery, a supercapacitytype device, an electrochomic device or as a component of a solvent.
