Abstract
Provided is a cylindrical battery cell having a simple structure, a simple assembly process, and high energy density. An electrode assembly is accommodated in an accommodation space of a can of the battery cell. One electrode of the electrode assembly is bonded to an end wall provided at a lower end portion of the can, and the other electrode of the electrode assembly is bonded to a cap covering an opening provided at an upper end portion of the can. The bonding is performed by irradiating a laser to the end wall and an outer surface of the cap to penetrate and weld the end wall and the outer surface of the cap. A first current collecting plate including a radially extending portion and an axially extending portion is interposed between the cap and the electrode assembly. The radially extending portion is bonded to a first electrode of the electrode assembly, and an upper end portion of the axially extending portion is bonded to a bottom surface of the cap.
