The invention relates to the application of at least one ester of general formula (I) to (V), whereby R<1>, R<2>, R<3>, R<4> are the same or different and each, independent of one another, represent a linear or branched-chain C1 to C4 alkyl group, (-CH2-CH2-O)n-CH3 with n=1 to 3, a C3 to C6 cycloalkyl group, and an aromatic hydrocarbon group which can be substituted. At least one of the groups R<1>, R<2>, R<3> or R<4> represents (-CH2-CH2-O)n-CH3 with n=1 to 3. The inventive ester can be used as a solvent in electrolyte systems for Li ion accumulators. |
