Abstract: A device and method for manufacturing a battery cell. The device includes: a roller moving mechanism, configured to control a first roller to move in a direction of a central axis of a battery cell, where the battery cell includes a case and a cover plate, the case and the cover plate being hermetically connected and forming a rolled edge structure that is turned outwards; and the first roller, configured to squeeze, when the roller moving mechanism controls the first roller to move in the direction of the central axis of the battery cell, the rolled edge structure by a first processing surface, to cause the rolled edge structure to be inclined in a direction close to the central axis of the battery cell.
