The electrolyte includes one or more salts and a silane. The silane has a silicon linked to one or more first substituents that each include a poly(alkylene oxide) moiety or a cyclic carbonate moiety. The silane can be linked to four of the first substituents. Alternately, the silane can be linked to the one or more first substituents and one or more second substituents that each exclude both a poly(alkylene oxide) moiety and a cyclic carbonate moiety.


Described are organosilicon electrolyte compositions having improved thermostability and electrochemical properties and electrochemical devices that contain the organosilicon electrolyte compositions.


Described are electrolyte compositions having at least one salt and at least one compound selected from the group consisting of: wherein a is from 1 to 3; b is 1 or 2; 4a+b2; X is a halogen; R can be alkoxy or substituted alkoxy, among other moieties, and R1 is alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, or substituted alkoxy. Also described are electrochemical devices that use the electrolyte composition.


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.
