Application: Battery cell and method for producing a battery cell (Patent ID: US20240213497A1)
The patent filed by Bayerische Motoren Werke AG describes a battery cell design that includes a cylindrical cell housing with a hollow cylinder, an electrically conductive closure plate, electrodes of different polarities separated by a separator, and an electrically conductive rod extending along the cylinder. The first polarity electrode is connected to the closure plate, while the second polarity electrode is connected to the rod, which is isolated from the closure plate. Additional elements such as intermediate plates and connecting elements are included to ensure proper electrical connections and mechanical integrity within the cell.
The battery cell design involves a method for producing the cell, which includes arranging electrodes and separators in the cylindrical cell housing, winding them around an electrically conductive rod, and establishing electrical connections between the electrodes and the closure plate and rod. The design aims to provide efficient electrical connections while maintaining insulation between components to enhance the overall performance and safety of the battery cell. Various configurations and elements such as intermediate plates, connecting elements, and a base plate with a breakable region are incorporated to facilitate assembly and operation of the battery cell.
