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

Patent number: 11050103Abstract: An electrochemical cell includes a housing, and an electrode assembly disposed in the housing. The electrode assembly comprises a positive electrode, a negative electrode and a separator disposed between the positive electrode and the negative electrode. The housing is formed of a first case half and a second case half. Each case half is formed of a metal foil laminate material and includes a wedge-shaped central recess that is surrounded by a flange. The flange of the first case half is joined to the flange of the second case half along a seal line that surrounds the respective central recesses. The central recesses cooperate to define an interior space of the housing that contains the electrode assembly, and the interior space has the shape of a rectangular prism. The seal line extends along a diagonal of a side of the rectangular prism. A method of forming the housing is described.Type: GrantFiled: July 9, 2019Date of Patent: June 29, 2021Assignees: Robert Bosch Battery Systems LLC, Robert Bosch GmbHInventor: Eugene Levin

Patent number: 10992005Abstract: An electrochemical pouch cell includes a pouch cell housing and an electrode assembly disposed in the housing. The housing is formed of a single blank that is progressively drawn to form first and second recesses in the sheet, where the first recess coincides with a portion of the second recess. The blank is then folded so that the recesses are aligned and open facing each other. The electrode assembly is disposed in the space defined within and between the recesses, and flange portions of the material surrounding the recesses are sealed together to form a sealed electrochemical cell in which one side of the cell is free of the flange. The progressive drawing process along with the configuration of the recesses allows the cell housing to have an increased depth relative to some conventional pouch cell housings.Type: GrantFiled: December 6, 2018Date of Patent: April 27, 2021Assignees: Robert Bosch Battery Systems LLC, Robert Bosch GmbHInventor: Eugene Levin

Patent number: 10266284Abstract: A tethered spacecraft has a first endmass and a second endmass with a telescoping stacer spring and a tether arranged between the endmasses. The spring is coiled around a center rod and initially contained within a housing, the spring being biased to push the first endmass away from the second endmass. The spring housing is affixed to the first endmass, a first end of the spring being affixed to the spring housing, and tether are affixed to spring at one end and to the second endmass at the other end. A pretensioned loop holds the endmasses abuttingly together, and a burnwire release mechanism cuts the loop to deploy the spring. Upon deployment, the spring extends to its full length to form a cylindrical boom, and the endmasses continue to move outward along the spring centerline until stopped by the tether.Type: GrantFiled: March 29, 2014Date of Patent: April 23, 2019Assignee: The United States of America, as represented by the Secretary of the NavyInventors: Shannon Coffey, Joseph A.
