摘要： The invention relates to a galvanic element comprising a negative electrode, which contains graphite-type carbons that are intercalated with lithium as an active material. In said element, the electrolyte only contains diethyl carbonate as the organic, aprotic solvent, lithium hexafluorophosphate as the supporting electrolyte, in addition to ethylene carbonate and between 0.2 and 5 wt. % vinylene carbonate. The fraction of vinylene carbonate preferably lies between 0.5 and 1.5 wt. % and the degree of crystallinity of the carbon material of the negative electrode is less than 80 %. The weight ratio of ethylene carbonate to diethyl carbonate is between 3 and 7. The electrolyte can also contain between 0.5 and 4 wt. % propane sultone and between 0.5 and 5 wt. % cyclohexyl benzole.

摘要： The invention relates to a galvanic element comprising at least one electrode that is intercalated with lithium, the positive electrode of said element containing a collector that essentially consists of aluminium. In said galvanic element, the collector that is coated with a positive electrode material comprises an oxide layer that has been at least partially broken up by calendering. Said oxide layer is broken up by a calendering process between two fixed metal rolls, which comprise a nip that is smaller than the initial thickness of the material to be calendered and said calendering process takes place immediately before or after the application of the positive electrode material. The transfer resistance to the collector is effectively reduced as the natural oxide layer of the aluminium is broken up in the aforementioned manner.

摘要： The invention relates to a galvanic element comprising an anode (4), a cathode (3), a separator (1) lying between said anode and cathode and an electrolyte. In said element, the separator is coated on at least one side with a thin, porous metallic layer. The metallic layer preferably consists of Al, Cu, Ag, V, Ti, Cr, Fe, Ni, Co, or alloys of said metals, or a corrosion-resistant stainless steel. The layer thickness of the metal on the separator (1) lies in particular within a range of 10 nm to 1,000 nm, preferably between 20 nm and 500 nm. The metallic layer is preferably applied to the separator (1) by vapour deposition. In particular, at least one of the electrodes (3, 4) is a lithium intercalating electrode.
