HALOGENATED ORGANOSILICON ELECTROLYTES, METHODS OF USING THEM, AND ELECTROCHEMICAL DEVICES CONTAINING THEM

摘要

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; 4≧“a”+“b”≧2; 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.

1. An electrolyte composition comprising at least one salt and at least one compound selected from the group consisting of: wherein subscript “a” is an integer of from 1 to 3; subscript “b” is 1 or 2; and 4≧“a”+“b”≧2; X is a halogen; R is selected from the group consisting of alkoxy, substituted alkoxy, Formula 1 moieties, and Formula II moieties: wherein R2 is an organic spacer; R3 is nil or an organic spacer; R4 is hydrogen, alkyl, or aryl; R5 is alkyl or aryl; subscript “c” is 1 or 2; and subscript “d” is from 1 to 12; and R1 is selected from the group consisting of alkyl, substituted alkyl, aryl, substituted aryl, alkoxy, and substituted alkoxy.
