Abstract: An adapter may include a first adapter and a second adapter disposed discretely. The first adapter may be configured to be connected to one of an electrode post or a tab. The second adapter may be configured to be connected to the other of the electrode post or the tab. The first adapter may substantially extend along a first direction. The second adapter may substantially extend along a second direction. The first direction may intersect the second direction. The first adapter may be connected to the second adapter by a conductive structure.

Abstract: Embodiments of the present disclosure provide an electrode assembly and a traction battery. The electrode assembly includes a plurality of tabs. The plurality of tabs is stacked to each other. At least one of the plurality of tabs includes a tab body and a free end connected to the tab body. The free end is formed into a bent portion through at least a single bending. The bent portion is stacked at a side of the tab body. In some specific embodiments, the tab is designed as a long tab with a long length. When ultrasonic welding is performed, the tab is bent to form the bent portion, and the bent portion is stacked on the tab body for the ultrasonic welding. In this case, since a thickness of a position where the ultrasonic welding is performed is increased, welding stability of the tab can be improved.

Abstract: A battery cell may include a housing, a first electrode assembly, and a second electrode assembly. The first electrode assembly may be disposed in the housing. The first electrode assembly may include a first body structure, and a first positive tab and a first negative tab that extend from the first body structure. The second electrode assembly may be disposed in the housing. The second electrode assembly may include a second body structure, and a second positive tab and a second negative tab that extend from the second body portion. The first body structure and the second body structure may be spaced out along a first direction.
