摘要： A battery cell housing which delimits an interior chamber for receiving a core material providing electrical energy. The battery cell housing consists of a housing shell and a housing cover. The housing shell has a floor and a housing shell wall extending coaxially to a housing axis, proceeding from the floor. The housing cover has a pot or bowl-shaped form. The housing cover is inserted into the housing shell wall at a distance from the floor after the core material has been introduced. The housing shell wall is mechanically connected to the housing cover by a folded joint, preferably a double folded joint. There is no integrally joined connection according to the invention. The folded joint is implemented radially inward toward the housing axis and is located closer to the housing axis than the outer surface of the housing shell wall, when viewed radially to the housing axis.

摘要： A method for manufacturing a cylindrical battery includes allowing a cylindrical battery case (5) with a bottom to contain an electrode plate group, carrying out a groove-forming processing on an outside periphery of an opening of the battery case, disposing a sealing plate in the opening of the battery case through a gasket, and crimping and sealing the end of the opening of the battery case. In a groove-forming processing process in which the battery case is rotated and a rotatable groove-forming roller (15) comes into contact with and is gradually pushed into the outside periphery of the opening of the battery case in a state where a core (12) corresponding to the diameter of the opening of the battery case is fitted into the opening of the battery case to support the battery case from the inner peripheral side, a rotational speed is increased in accordance with increase in the diameter of the battery case so that the push-in amount of the groove-forming roller per unit rotation perimeter and per unit of time approximately becomes a certain value even if the size of the diameter of the battery case varies. Thus, a common groove-forming processing device can carry out the groove-forming processing on battery cases of different battery sizes to manufacture cylindrical batteries.
