Patent number: 11111576Abstract: According to a method for producing a nanostructured electrode for an electrochemical cell, in which active material is applied to an electrically conductive substrate, the active material is deposited on the electrically conductive substrate by magnetron sputtering in one process step, a ceramic target comprising an electrode material having an additional carbon proportion between 0.1 and 25% by weight is used, the substrate being kept at temperatures between 400° C. and 1200° C. during the deposition, in such a way that a fibrous porous network is formed.Type: GrantFiled: April 27, 2016Date of Patent: September 7, 2021Assignee: Forschungszentrum Juelich GmbHInventors: Aiko Buenting, Sven Uhlenbruck

Patent number: 10763549Abstract: A method for producing at least one electrochemical cell of a solid-state battery, comprising a mixed-conducting anode, a mixed-conducting cathode, and an interposed electrolyte, is characterized in that a mixed-conducting anode and a mixed-conducting cathode are initially produced or provided. The surface of at least one of the two electrodes is modified by way of an additional method step in such a way that the electronic conductivity perpendicular to the cell is reduced to less than 10?8 S/cm in a layer of the electrode near the surface. The anode and cathode are then assembled to form a solid-state battery in such a way that the surface-modified layer of at least one electrode is disposed as an electrolyte layer between the anode and cathode, and the mixed-conducting electrodes are thereby electronically separated.Type: GrantFiled: September 5, 2014Date of Patent: September 1, 2020Assignee: FORSCHUNGZENTRUM JUELICH GMBHInventors: Martin Finsterbusch, Chih-Long Tsai, Sven Uhlenbruck, Hans Peter Buchkremer

Patent number: 10403881Abstract: A method for producing a ceramic cathode layer on an electrically conductive substrate includes applying a coating to the electrically conductive substrate, the coating being in a form of a suspension including at least one suspending agent and at least one ceramic material. The method further includes heating the coating in a reducing atmosphere such that the ceramic material is completely or in part reduced to a fusible reaction product, heating the coating in a reducing atmosphere to temperatures above the melting point of the reaction product so as to form a melt, densifying or sintering the coating in a reducing atmosphere at temperatures that are 100° C. greater than a melting temperature of the reaction product, and reoxidizing the densified or sintered coating in an oxidizing atmosphere in a temperature range of between 400° C. and 1,200° C.Type: GrantFiled: December 9, 2016Date of Patent: September 3, 2019Assignee: FORSCHUNGSZENTRUM JUELICH GMBHInventors: Juergen Dornseiffer, Hans-Gregor Gehrke, Manuel Krott, Olivier Guillon, Sven Uhlenbruck

Patent number: 10312540Abstract: A cathode-electrolyte-anode unit for an electrochemical functional device, in particular a high-temperature fuel cell. The unit has a multi-layer solid-state electrolyte arranged between a porous anode and a porous cathode. The solid-state electrolyte is produced by a vapor deposition process and has a sandwich-type structure consisting of at least one first layer with a lower oxygen content, and at least one second layer with a higher oxygen content. The individual layers have substantially the same composition, with the exception of oxygen.Type: GrantFiled: May 20, 2014Date of Patent: June 4, 2019Assignees: Plansee Composite Materials GmbH, Forschungszentrum Juelich GmbH, Fraunhofer Gesellschaft zur Foerderung der angewandten Forschung e.V.Inventors: Markus Haydn, Matthias Ruettinger, Thomas Franco, Sven Uhlenbruck, Thomas Jung, Kai Ortner

Patent number: 10230141Abstract: A rechargeable energy storage device according to the invention is based on a metal-air battery, in which a gas electrode is used and an ion-conducting or proton-conducting membrane is used as the electrolyte. In contrast to the known metal-air batteries, the active component on the side of the electrolyte membrane opposite the gas electrode is present in the form of a liquid medium in the energy storage device according to the invention. The liquid-medium/gas battery according to the invention comprises a receptacle, which includes a medium in liquid form as the active material at the operating temperature of the battery.Type: GrantFiled: February 3, 2015Date of Patent: March 12, 2019Assignee: FORSCHUNGSZENTRUM JUELICH GMBHInventors: Sven Uhlenbruck, Martin Finsterbusch, Eva Maria Hammer, Hans Peter Buchkremer
