Patent ID: 7679884

Claim:
An electrolyte comprising a cationic moiety comprising the following structure: wherein R 1 , R 2 and R 3 are the same or different and each is selected from the group consisting of alkyl moieties of less than ten carbons and hydrogen, wherein at least one of R 1 , R 2 and R 3 are alkyl moieties; wherein R 4 is selected from the group consisting of alkyl moieties of less than ten carbons, and alkoxy groups of less than ten carbons; wherein R 5 , R 6 and R 7 are the same or different and each is selected from the group consisting of alkyl moieties of less than ten carbons, hydrogen and —O—SiR 8 R 9 R 10 , wherein R 8 , R 9 and R 10 are the same or different and each is selected from the group consisting of alkyl moieties with less than ten carbons and hydrogen; wherein the electrolyte further comprises an anion such that the cationic moiety is present in a salt; and wherein the anion is selected from the group consisting of halogen anions, (CF 3 SO 2 ) 2 N − , B(C 2 O 4 ) 2 − and tetrafluoroborate anion.
