Abstract: The present application provides a battery cell, a battery, and an electrical device. The battery cell comprises a case, a cell, a first expandable member, and a second expandable member. The cell is arranged inside the case. There is a gap between an outer wall of the cell and an inner wall of the case. The first and second expandable members are both arranged in the gap and are configured to expand when encountering an electrolyte solution to fill the gap. The first and second expandable members are spaced apart and can expand when encountering the electrolyte solution. After expansion, the gap between the cell and the case can be reduced, thereby restricting relative movement between the cell and the case, reducing the possibility of fatigue fracture of connecting sheets, and contributing to protecting tabs.
