Abstract
An embodiment of the present application provides a battery cell, a battery, a power consumption device, and a manufacturing equipment and method for a battery cell. The battery cell includes a housing, an electrode assembly, an end cover to cover the housing, and an electrode terminal installed on the end cover and electrically connected with the electrode assembly. The end cover includes a first body and a first convex portion, and the first convex portion extends from the first inner surface of the first body along a direction facing the electrode assembly, a position on the first body corresponding to the first convex portion is formed with a first concave portion recessed from the first outer surface opposite to the first inner surface along the direction facing the electrode assembly, the first concave portion is configured to accommodate the electrode terminal. The battery cell can effectively increase the battery capacity.
