BATTERY, ELECTRICAL DEVICE, AND METHOD AND DEVICE FOR MANUFACTURING BATTERY

This application discloses 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 on two end faces of each of the battery cells along the first direction respectively; and a busbar component, configured to connect the two electrode terminals to implement electrical connection between two battery cells. The busbar component includes a flexible bend portion. The flexible bend portion is configured to adjust a relative position between the two electrode terminals. A maximum width of the flexible bend portion along the first direction is greater than a distance between the two electrode terminals. The flexible bend portion disposed in the busbar component can be bent in various forms to meet a requirement of electrically connecting the two battery cells arranged at a variety of relative positions.
