Method for the production of a battery with a prismatic battery housing, comprising • a bottom element • a lid element disposed parallel to said bottom element, having the same size and shape, as well as • four side elements connecting the bottom element and the lid element, which together define an enclosed interior, in which functional parts of the battery, especially at least one positive and at least one negative battery electrode as well as at least one separator separating the electrodes, are arranged, wherein • one of the elements comprises at least one through hole, through which a contact pole is led, which contact pole is electrically connected to at least one of the electrodes disposed in the interior, characterized in that • the battery housing is assembled from two prefabricated housing parts by welding, of which • the first housing part comprises at least a partial region of the element comprising the at least one through hole as well as at least a partial region of a second element, bordering on the element comprising the at least one through hole, and • the second housing part comprises all the elements and/or partial regions of elements which are not part of the first housing part, wherein • the two prefabricated housing parts joined together form a cuboidal housing with six rectangular surfaces, eight corners and twelve edges, whose base surface is formed by the bottom element and has four corners A, B, C and D and whose top surface is formed by the lid element and has four corners E, F, G and H, wherein the corner E is disposed above the corner A, the corner F above the corner B, the corner G above the corner C and the corner H above the corner D, and • the two housing parts are joined together along the lines of connection A-B-G-H-A, F-CG-DH-E-F, G-H-AE-BF-G or A-B-F-G-H-D-A. • a bottom element • a lid element disposed parallel to said bottom element, having the same size and shape, as well as • four side elements connecting the bottom element and the lid element, which together define an enclosed interior, in which functional parts of the battery, especially at least one positive and at least one negative battery electrode as well as at least one separator separating the electrodes, are arranged, wherein • one of the elements comprises at least one through hole, through which a contact pole is led, which contact pole is electrically connected to at least one of the electrodes disposed in the interior, characterized in that • the battery housing is assembled from two prefabricated housing parts by welding, of which • the first housing part comprises at least a partial region of the element comprising the at least one through hole as well as at least a partial region of a second element, bordering on the element comprising the at least one through hole, and • the second housing part comprises all the elements and/or partial regions of elements which are not part of the first housing part, wherein • the two prefabricated housing parts joined together form a cuboidal housing with six rectangular surfaces, eight corners and twelve edges, whose base surface is formed by the bottom element and has four corners A, B, C and D and whose top surface is formed by the lid element and has four corners E, F, G and H, wherein the corner E is disposed above the corner A, the corner F above the corner B, the corner G above the corner C and the corner H above the corner D, and • the two housing parts are joined together along the lines of connection A-B-G-H-A, F-CG-DH-E-F, G-H-AE-BF-G or A-B-F-G-H-D-A.
