## Abstract

Described herein are liquid, organosilicon compounds that including a substituent that is a cyano (—CN), cyanate (—OCN), isocyanate (—NCO), thiocyanate (—SCN) or isothiocyanate (—NCS). The organosilicon compounds are useful in electrolyte compositions and can be used in any electrochemical device where electrolytes are conventionally used.
