Abstract
Example illustrations are directed to methods and apparatuses comprising battery cells having weld joints. In an example method, a laser is moved to a shoulder of a battery cell. The method may further include micro welding with the laser a first line segment on the shoulder of the battery cell and moving the laser a distance on the shoulder of the battery cell. The method may also comprise micro welding with the laser a second line segment on the shoulder of the battery cell in response to moving the laser the distance. Example battery cell assemblies, e.g., for a battery pack, may have a battery cell and a weld joint on a shoulder of the battery cell. The weld joint may include a first micro weld line segment and a second micro weld line segment separated by a distance.
Claims20
A method, comprising:
- moving a laser to a shoulder of a battery cell;
- micro welding with the laser a first line segment on the shoulder of the battery cell;
- micro welding with the laser a second line segment on the shoulder of the battery cell;
- and
- micro welding with the laser a third line segment on the shoulder, wherein:
- the first, second, and third line segments are laterally adjacent to each other and equally spaced apart.
A battery cell assembly, comprising:
- a battery cell;
- a weld joint on a shoulder of the battery cell, wherein the weld joint comprises a first micro weld line segment, a second micro weld line segment, and a third micro weld line segment, wherein the first micro weld line segment, second micro weld line segment, and third micro weld line segment are laterally adjacent to each other and equally spaced apart.
A battery pack, comprising:
- a plurality of battery cells;
- a plurality of weld joints, each battery cell having one of the weld joints on a shoulder of the battery cell, respectively, each weld joint comprising a first micro weld line segment, a second micro weld line segment, and a third micro weld line segment, wherein the first micro weld line segment, second micro weld line segment, and third micro weld line segment are laterally adjacent to each other and equally spaced apart.
