Patent ID: 8829201

Claim:
An electrolyte formulation comprising at least one compound of the Formula (I) Kt + [B(CN) 2 F 2 ] − (I) in which Kt + is an organic cation selected from the group of where the substituents R 1′ to R 10′ each, independently of one another, denote H with the assumption that R 1′ and R 4′ are not simultaneously H, straight-chain or branched alkyl having 1-20 C atoms, which optionally may be fluorinated, straight-chain or branched alkenyl having 2-20 C atoms and one or more double bonds, which optionally may be fluorinated, straight-chain or branched alkynyl having 2-20 C atoms and one or more triple bonds which optionally may be fluorinated or straight-chain or branched alkoxyalkyl having 2 to 8 C atoms, one or more redox couples, optionally one or more further salts, and optionally one or more constituents.
