Zusammenfassung:	A method for producing a battery includes depositing, via sputter deposition, a coating on at least a portion of a cup shaped first housing part of the battery. The coating includes aluminium, chromium, tin, and/or an alloy having two or more of the group consisting of aluminium, chromium, and tin. The method also includes establishing an electrical connection between a current conductor of the battery and the cup-shaped first housing part of the battery and assembling the cup-shaped first housing part of the battery and a second housing part of the battery to form a housing of the battery. The housing has an interior space that includes a composite body including a positive electrode, a negative electrode, a separator, and the current conductor. The cup-shaped first housing part has a circular or oval bottom and a ring-shaped side wall.
