摘要:
Provided are a cell capable of preventing damage to an insulating gasket by spatter scattered when a battery case and a cover plate are laser-welded together, and thereby ensuring sealability of a cell case and a method for manufacturing the cell. A shielding member is arranged between a weld line and at least a portion of the insulating gasket adjacent to the weld line. Since the shielding member blocks the spatter scattered toward the insulating gasket, the insulating gasket is not damaged by the spatter. The insulating gasket is not damaged, so that adhesion between the insulating gasket and the cover plate is not lowered, and the sealability of the cell case is ensured.
