Abstract: This application relates to an adapter assembly, a battery cell, a battery, and an electrical device. The adapter assembly includes: a current collecting component, including a terminal connecting portion, a fuse portion, and a tab connecting portion, where the fuse portion is connected between the terminal connecting portion and the tab connecting portion; and an insulation protection component, wrapping the fuse portion. The insulation protection component is configured to keep a fixed relative position between the terminal connecting portion and the tab connecting portion when the fuse portion is blown. A first mating portion is formed on at least one surface of the fuse portion in a thickness direction. At least a part of one of the first mating portion or the insulation protection component protrudes along the thickness direction and is embedded inside the other of the first mating portion or the insulation protection component.

Abstract: A device for repairing burrs of an electrode plate is provided, which includes a plurality of shaping rollers, wherein a shaping surface is formed on an outer surface of each of the shaping rollers, and along a conveying direction of an electrode plate, included angles between the plurality of shaping surfaces and a surface of the electrode plate decrease in sequence. The device for repairing burrs of an electrode plate gradually decreases the angle between the burrs and the electrode plate until the burrs are flattened, and the end-surface burrs are finally transformed into flat-surface burrs, thereby reducing the safety risk of batteries.
