Patent number: 5514489Abstract: An electrochemical storage cell is bounded by a metallic casing and has a cup-shaped solid electrolyte on the inside which separates an anode compartment from a cathode compartment. The storage cell is externally closed in a leak-proof and gas-tight manner. A closure of the cell has an additional seal with two mutually overlapping components between which an insulating ring is disposed.Type: GrantFiled: October 24, 1994Date of Patent: May 7, 1996Assignee: ABB Patent GmbHInventors: Franz Lenz, Gunther Steinleitner

Patent number: 4927475Abstract: A process for joining components having ceramic and metallic joining surfaces provides a permanent and complete joint with ceramic surfaces despite metal-oxide layers on the metal or metal-alloy joining surfaces. A glass coating is applied to the ceramic joining surface before joining. The glass contains at least 5 to 20% by weight of Na.sub.2 O, 30 to 60% by weight of B.sub.2 O.sub.3 and 20 to 60% by weight of SiO.sub.2. The surfaces of the components to be joined are then permanently joined to each other at a specified temperature and a specified pressure.Type: GrantFiled: October 31, 1988Date of Patent: May 22, 1990Assignee: Asea Brown Boveri AktiengesellschaftInventors: Gunther Steinleitner, Philipp Roze

Patent number: 4853303Abstract: An electrochemical storage cell based on sodium and sulphur includes a metallic housing. A solid electrolyte disposed in the housing defines an anode space and a cathode space mutually separated by the solid electrolyte and outwardly bounded by the housing. A felt is disposed in the cathode space to form an electrode. The felt is impregnated with sulphur and folded at least twice. The felt has graphite or carbon fibers disposed substantially perpendicular to the longitudinal axis of the storage cell and substantially perpendicular to the surface of the solid electrolyte.Type: GrantFiled: May 12, 1988Date of Patent: August 1, 1989Assignee: BBC Brown Boveri AktiengesellschaftInventors: Gunther Steinleitner, Stefan Mennicke, Philbert Feindler, Herbert Klein, Sigisfredo Maldonado-Zagal

Patent number: 4761353Abstract: An electrochemical storage cell based on sodium and sulfur having an anode space and a cathode space, which are separated from one another by a solid electrolyte and are defined at least in some areas by a metal housing wherein the cathode space, in order to form the electrode, is filled with filamentary material of graphite or carbon that is saturated with sulfur. Between the solid electrolyte and the electrode of the cathode space, at least one intermediate film is provided, by means of which a sliding of the electrode along the surface of the solid electrolyte is assured.Type: GrantFiled: May 1, 1987Date of Patent: August 2, 1988Assignee: Brown, Boveri & Cie AGInventors: Reinhard Knodler, Werner Bansemir, Stefan Mennicke, Gunther Steinleitner

Patent number: 4515874Abstract: Electrochemical storage cell of the alkali metal and chalcogen type with at least one anode space for the alkali metal anolyte, and a cathode space for the chalcogen catholyte, with the anode space and the cathode space separated from each other by an alkali ion-conducting solid electrolyte wall, the improvement comprising the addition in the anode space of sodium and of a capturing material with O.sub.2 -getter properties in an amount sufficient to absorb detrimental bound or free oxygen.Type: GrantFiled: April 15, 1982Date of Patent: May 7, 1985Assignee: Brown, Boveri & Cie AgInventor: Gunther Steinleitner
-
Patent number: 4446213Abstract: Electrochemical storage cell or battery with at least one anode space for receiving the anolyte and one cathode space for receiving the catholyte which spaces are separated from each other by an alkali ion-conducting solid electrolyte and are bounded at least in some places by a metallic housing. A safety space which is subdivided into at least two safety zones, adjoins at least in some places, the solid electrolyte.Type: GrantFiled: May 3, 1982Date of Patent: May 1, 1984Assignee: Brown, Boveri & Cie AGInventor: Gunther Steinleitner

Patent number: 4413043Abstract: Electrochemical chemical storage cell or battery of the alkali metal and chalcogen type with an anode space and a cathode separated from each other by an alkali-ion conducting solid electrolyte. The cup-shaped solid electrolyte of beta-aluminum oxide is fastened at its open end in a force-locking manner by means of a joining material to an annular insulating body. The joining material contains a mixture of a glass powder and a ceramic powder suspended in a liquid with high viscosity.Type: GrantFiled: August 18, 1981Date of Patent: November 1, 1983Assignee: Brown, Boveri & Cie AGInventors: Gunther Steinleitner, Wilhelm Haar

Patent number: 4401731Abstract: An electrochemical storage cell based on alkali metal and chalcogen with an anode space and a cathode space separated from each other by an alkali ion-conducting solid electrolyte. The cell is bounded by a metallic housing. A closure seals the top of the cell in a sealing zone. The open end of the can shaped solid electrolyte disposed in the interior of the cell is bonded by a bonding material to a ring-shaped insulating part which defines the two reactant space relative to each other in the sealing zone. In the sealing zone of the storage cell closure, the metallic housing as well as the solid electrolyte and the insulating part fastened to it are covered by a protective layer.Type: GrantFiled: August 18, 1981Date of Patent: August 30, 1983Assignee: Brown, Boveri and Cie AGInventor: Gunther Steinleitner
