Patent number: 11638948Abstract: A forming device is configured to form metal laminated sheet material into a tray-shaped case half while allowing the material to form pleats in the corners of the recess during the forming process while preventing formation of pleats along the flange. The device forms the flange so that excess material in the corners of the case halves is arranged in an undulating shape. As a result, the flange has a waved or ruffled configuration at each corner. Two such case halves are sealed together along the flange to form a reliably sealed package. A method of forming pouch cell is also described.Type: GrantFiled: November 22, 2017Date of Patent: May 2, 2023Assignees: Robert Bosch Battery Systems LLC, Robert Bosch GmbHInventors: Mark Kotik, Eugene Levin, David Sarazin

Patent number: 11588183Abstract: An electrochemical cell includes a cell housing and an electrode assembly disposed in the cell housing. The electrode assembly includes an electrode pair that is arranged to form a winding having a polygonal spiral wound shape in which a radius of the corner portions of each turn of the winding is constant, regardless of the number of turns. In addition, a length of the linear portions of one turn of the winding is different than a length of the linear portions of another turn of the winding. Since each turn of the winding includes the corner portions having a desired radius, the volumetric efficiency of the electrode assembly including the winding within a cell housing is improved relative to some cells that use conventional windings. An apparatus and method of forming a polygonal spiral wound winding are disclosed.Type: GrantFiled: December 20, 2018Date of Patent: February 21, 2023Assignees: Robert Bosch Battery Systems LLC, Robert Bosch GmbHInventors: Mehul Botadra, Eugene Levin, Mark Kotik, Paul Frick
