Abstract: A liquid formulation is provided. The liquid formulation contains at least one aprotic organic solvent, at least one lithium salt, at least 1.5% by weight of a compound of formula (I) based on a total weight of the liquid formulation, essentially no 1,2,3,4-tetrahydronaphthalene, and optionally at least one additive other than (C): where R1 is C1-C6-alkyl, phenyl, or 2- and 4-pyridyl, which may be substituted with one or more moieties of F, CN, C1-C4-alkyl and CF3; each R2 is independently C1-C4-alkyl, CN, or fluorine; a is a number of from zero to four; and X is O—SO2—R1 or hydrogen.
