Abstract
The invention relates to an electrolyte solution for double-layered capacitors comprising at least one conductor salt which comprises a cation having a maximum diameter of < 9,20 ~ having additional substituents on the central atom which are not equal. Also, comprising at least one solution which contains a functional group which is selected from lactones and nitriles. Said type of electrolyte solutions have, compared to traditional electrolyte solutions, improved behaviour at low temperatures when acetonitrile is selected as a solvent such that the double-layered capacitors provided for the inventive electrolyte solutions have improved electric properties at low temperatures.
