Abstract

The object of the present invention is to provide a sealed battery and a manufacturing method of a sealed battery that suppresses cracking incident to welding using an energy beam, such as a laser beam, when a material such as an aluminum alloy is used for the external casing and the cover plate, with keeping the productivity as high as possible. In order to realize the object, a rib is formed on the cover plate, and the thickness of the external casing at the rim is made small, and the rib and the rim of the external casing are welded together in manufacturing the sealed battery.
Then, the closure cap and the external casing are welded together using a laser the energy distribution of which has a flat part in manufacturing the sealed battery to realize the object. In addition, the closure cap and the external casing are welded together while the molten part is gradually cooled in manufacturing the sealed battery to realize the object.
