Zusammenfassung: | A method for manufacturing galvanic elements having a liquid organic electrolyte that contain an electrode-separator assembly that has at least one lithium intercalating electrode in whose polymer matrix insoluble, electrochemically active materials are finely distributed in the polymer involved, the electrolyte contains about 2% to about 15% by weight of a hydrocarbon-oxygen compound (carbonate) that has a central carbon atom, to which one oxygen atom is doubly bonded and two oxygen are singly bonded, where the singly bonded oxygen is not saturated by any other atoms or groups and a hydrocarbon chain having a length of four carbon atoms or less is bonded to each of those singly bonded oxygen atoms and these two chains differ by at least one, but no more than three, CH2 groups, and this electrode-separator assembly is initially impregnated with this electrolyte, then cut to size, and subsequently inserted into a housing. The electrode-separator assemblies may be laminated onto conductors and/or counterelectrodes prior to their being impregnated with the electrolyte and may also be rolled up and then impregnated. |
