The invention relates to an electrolyte solution that is devoid of acetonitrile and only contains one solvent. Said solution has a conductivity of at least 20 mS/cm or more and comprises the following constituents: A) a supporting electrolyte or blend of supporting electrolytes with a concentration > 1.7 mol/l, which contains at least one ion with an asymmetrically substituted atom; B) a solvent which is either a lactone or a carbonate. The inventive electrolyte solutions have a high conductivity with a high voltage stability and a high boiling point. |
