    摘要： Some embodiments of this application provide a battery cell, a battery, an electrical device, and a method and an apparatus for manufacturing a battery cell. The battery cell includes a housing, a first electrode assembly, and a second electrode assembly. The first electrode assembly is disposed in the housing. The first electrode assembly includes a first body portion, and a first positive tab and a first negative tab that extend from the first body portion. The second electrode assembly is disposed in the housing. The second electrode assembly includes a second body portion, and a second positive tab and a second negative tab that extend from the second body portion. The first body portion and the second body portion are spaced out along a first direction. The first positive tab and the first negative tab are disposed at an end of the first body portion, where the end is closer to the second body portion along the first direction. The second positive tab and the second negative tab are disposed at an end of the second body portion, where the end is closer to the first body portion along the first direction.

    摘要： Embodiments of this application provide a battery, an electrical device, and a method and device for manufacturing a battery. The battery includes: a plurality of battery cells arranged along a first direction, where electrode terminals are disposed respectively at both ends of each of the battery cells along the first direction separately, so that two battery cells include two electrode terminals opposite to each other along the first direction. Surface contact is formed between two end faces opposite to each other along the first direction and belonging to the two electrode terminals. The two electrode terminals are configured to be fixedly connected along an outer periphery of at least one of the two end faces to implement electrical connection between the two battery cells. The technical solution of embodiments of this application can increase the connection strength and heat conduction area between battery cells, and save space.
