Abstract
A battery cell, a battery pack, an electric device, and an energy storage device used in the technical field of batteries. The battery cell comprises a casing and at least two groups of bare cells. An accommodating cavity is formed in the casing; the at least two groups of bare cells are disposed in the accommodating cavity; each bare cell comprises at least two layers of electrode sheets; the at least two layers of electrode sheets are stacked in a thickness direction; the same group of bare cells are stacked in the thickness direction; and different groups of bare cells are spread in a plane perpendicular to the thickness direction. Different groups of bare cells are spread in the plane perpendicular to the thickness direction, thereby reducing the number of stacked bare cells, and the major surfaces of different groups of bare cells will not press each other, so that the swelling force of the major surfaces can be reduced, the breakage risk of the electrode sheets is reduced, and the service life of the battery cell is prolonged.
