Patent number: 11233286Abstract: The invention relates to a rechargeable battery comprising a battery housing which has a cell cavity, or several cell cavities separated by dividing walls. One or more of the cell cavities have at least one respective positive and negative electrode, separated from each other by at least one separator, and a liquid electrolyte. One or more of the cell cavities have a respective wall element, which partitions the respective cell cavity into at least two volume chambers which communicate with one another. At least in the lower regions of the volume chambers, a communicating connection between the volume chambers for the liquid electrolytes is provided and in the upper region of the volume chambers, a pressure compensation connection between the volume chambers for assuring equal air pressure in the volume chambers communicating chambers is provided. Also disclosed is a wall element for such a rechargeable battery, and a battery housing.Type: GrantFiled: March 25, 2019Date of Patent: January 25, 2022Assignee: Clarios Germany GmbH & Co. KGInventors: Dirk Bremer, Peter Streuer

Patent number: 9508972Abstract: The invention relates to a venting device (1) for an electrochemical battery (90). The venting device comprises at least one inlet opening (2) for receiving gases venting from the battery (90), at least one outlet opening (3) for venting the gases received from the battery (90), and at least one flame arrester element (4). The inlet opening (2) is in communication with the outlet opening (3) via the flame arrester element (4). An explosion chamber (5, 6) is located within the venting device (1) on the side of the flame arrester element (4) which is directed to the outlet opening (3). The explosion chamber (5, 6) is arranged for developing and temporarily storing an explosive mixture of the gases received from the battery (90) and oxygen from the ambient air, which explodes in case a flame occurs within the explosion chamber (5, 6), thereby blowing off the flame.Type: GrantFiled: March 2, 2012Date of Patent: November 29, 2016Assignees: Johnson Controls Technology Company, Johnson Controls Autobatterie GmbH & Co. KGAAInventors: Ingo Koch, Peter Streuer, Armin Staffeldt, Doreen Lucht, Jerome Heiman, Donald Caldwell, Dirk Bremer
