Stable electrolyte counteranions for capacitors

The invention relates to electrolyte salts for electrochemical devices of improved physical, chemical and electrochemical stability. The improvement resides in the use of anions of salts of the formula comprising: i) (B 12 F x Z 12-x ) 2- wherein Z comprises at least one of H, Cl, Br or OR; R compri...

Zusammenfassung:	The invention relates to electrolyte salts for electrochemical devices of improved physical, chemical and electrochemical stability. The improvement resides in the use of anions of salts of the formula comprising: i) (B 12 F x Z 12-x ) 2- wherein Z comprises at least one of H, Cl, Br or OR; R comprises at least one of H, alkyl or fluoroalkyl, or at least one polymer and x is at least 3 on an average basis but not more than 12; ii) ((R'R''R''')NB 12 F x Z (11-x) ) - , wherein N is bonded to B and each of R', R", R''' comprise a member independently selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl and a polymer; Z comprises H, Cl, Br, or OR, where R comprises H, alkyl or perfluoroalkyl or a polymer, and x is an integer from 0 to 11; or iii) (R""CB 11 F x Z (11-x) ) - , wherein R"" is bonded to C and comprises a member selected from the group consisting of hydrogen, alkyl, cycloalkyl, aryl, and a polymer, Z comprises H, Cl, Br, or OR, wherein R comprises H, alkyl or perfluoroalkyl or a polymer, and x is an integer from 0 to 11.
