Patent number: 7141333Abstract: A method for producing an electrochemical element having at least one lithium-intercollating electrode and an organic electrolyte, at least one positive electrode, at least one negative electrode and at least one separator are joined together to form an element, with the separator being a porous matrix composed of at least about 60% by weight of a ceramic material A, which contains lithium ions, and a polymer as a binding agent. The resulting element is then introduced into a housing and impregnated with a liquid organic electrolyte B, whose conductive salt contains lithium ions, so that the ionic total conductivity of the separator is formed by adding the ion conductivities of A and B and the reciprocal of the specific contact resistance of the phase boundary between A and B, and is then closed such that it is sealed. A copolymer composed of vinylidene fluoride and hexafluoropropylene is used as the binder polymer. Material A is a naturally occurring mineral.Type: GrantFiled: April 29, 2003Date of Patent: November 28, 2006Assignee: Varta Microbattery GmbHInventors: Peter Birke, Fatima Birke-Salam, Thomas Woehrle, Peter Haug, Konrad Holl, Heinrich Stelzig, Dejan Ilic

Patent number: 6780545Abstract: 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.Type: GrantFiled: December 3, 2002Date of Patent: August 24, 2004Assignee: Varta Microbattery GmbHInventors: Fatima Birke-Salam, Peter Birke, Konrad Holl, Heinrich Stelzig, Dejan Illic

Publication number: 20030232241Abstract: An electrochemical element has at least one lithium-intercalating electrode and a thin flexible housing composed of two metal sheets, which rest directly on the electrodes and are connected to one another in a sealing manner via an adhesive or sealing layer. At least one of the metal sheets is provided on the outside with a plastic layer, which increases the robustness and strength. An adhesion layer is arranged between the metal sheet and the plastic layer. The metal sheet is composed, for example, of copper. The plastic layer is composed, for example, of polyimide. The adhesion layer is based, for example, on rubber.Type: ApplicationFiled: June 9, 2003Publication date: December 18, 2003Applicant: VARTA Microbattery GmbH, a corporation of GermanyInventors: Thomas Woehrle, Peter Birke, Fatima Birke-Salam, Claudia Rathmann, Stefan Fuerst, Heinrich Stelzig, Dejan Ilic
