Abstract: A battery cell, including a first electrode plate, a second electrode plate, a separator, and a first electrode tab. The separator is disposed between the first electrode plate and the second electrode plate. The first electrode plate, the second electrode plate, and the separator are wound along a length direction of the first electrode plate. The first electrode tab is located at an end in a width direction of the first electrode plate. In the length direction of the first electrode plate, the first electrode plate includes a first edge, and a first notch is disposed at the first edge.
