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.
Claims10
An electrolyte composition comprising a compound of Formula III,
- wherein R1, R2, and R3 are the same or different and are independently selected from the group consisting of C1 to C6 linear or branched alkyl and fluorine, and wherein at least one of R1, R2, or R3 is fluorine;
- “Spacer” is selected from the group consisting of C3 to C6 linear or branched alkylene, alkenylene, or alkynylene;
- and
- R4 is selected from the group consisting of cyano (—CN), cyanate (—OCN), isocyanate (—NCO), thiocyanate (—SCN) and isothiocyanate (—NCS);
- in combination with a lithium-containing salt.
