摘要：
The present application discloses a cell, a battery, a manufacturing method of a cell, and an electronic device. The sealant comprises an exposed portion extending out of the top sealing, the exposed portion is provided with an avoidance area and/or a thinning area, and the avoidance area and/or the thinning area is provided for bending of the tab. The exposed portion of the sealant can bend along the avoidance area and/or the thinning area, so that the length of the sealant after bending in a length direction of the cell is reduced, which is conductive to reducing the packaging space of the cell and improving the capacity of the cell.
