Cylindrical battery |
| abstract |
The purpose of the present invention is to provide a cylindrical battery wherein a central part of a sealing plate which is fixed by swaging to an opening of an external packaging can is configured to be warped toward the inner part of the battery. The cylindrical battery according to one embodiment of the present invention is provided with: an electrode body in which a positive electrode plate and a negative electrode plate are rolled with a separator being disposed therebetween; an electrolytic solution; an external packaging can which has a bottomed cylindrical shape and which houses the electrode body and the electrolytic solution; and a sealing plate (22) which is fixed by swaging to an opening of the external packaging can with a gasket therebetween. The sealing plate (22) has a circular shape as viewed in a planar view. In the sealing plate (22), prior to the swage fixing, an outer peripheral edge (27) to be fixed by swaging to the external packaging can is formed inclined so as to be directed to the inner part of the battery, toward radially outward. |
