Abstract: A battery cell includes a casing provided with openings at two ends of the casing in a first direction, a first end cap and a second end cap connected to the casing and configured to close the openings at the two ends of the casing, respectively, and a connecting piece disposed in the casing and configured to be connected to the first end cap or be connected to the first end cap and the second end cap. The battery cell is provided with a weak structure at one of the two ends. A connecting force between the connecting piece and the first end cap is greater than a connecting force between the connecting piece and the second end cap. A connecting position where the connecting piece is connected to the first end cap is located in an area surrounded by the weak structure.
