An electrolyte solution proposed for double layer capacitors contains at least one conducting salt comprising a cation having a maximum diameter&#x3c;9.20 &#xc1; which additionally comprises substituents on the central atom which are not all the same and further contains at least one solvent comprising a functional group selected from lactones and nitrites. Such electrolyte solutions are superior to conventional electrolyte solutions at low temperatures when acetonitrile is the solvent, so that double layer capacitors provided with electrolyte solutions according to the invention have improved electrical properties at low temperatures.

Electrolyte solution for double-layered capacitors and double-layered capacitor containing said electrolyte solution

A double-layer capacitor includes a first electrode having a first polarity, a second electrode having a second polarity, the first polarity being different from the second polarity, and an electrolyte that is in contact with the first electrode and the second electrode. The first electrode has a first charge of the first polarity and the second electrode has a second charge of the second polarity, and maximum values of the first charge and the second charge are substantially equal.

The invention describes a method and a device for introducing volatile liquids into housings of electrical components, in particular of passive electrical components or of electrochemical cells, and for closing the housings. The method can be carried out using an evacuable chamber (), a conveyor device () for conveying the components (), a gas pressure device () for generating a gas pressure atmosphere in the chamber, a filling device () for introducing a volatile liquid into a component (), a closing device () for closing the component (), and using a programmable sequence control means (), which controls the conveyor device (), the gas pressure device (), the filling device () and/or the closing device () in such a way that these devices interact in a predetermined manner.
