A battery module comprising:
- a housing element (2) made of a metallic material (3), and a lid element (4) made of a metal material (5), which are connected to one another while forming of a common internal space (6) configured so as to accommodate a plurality of battery cells (7) by the formation of a plurality of plastic deformations (8) of the lid element (4) that are spaced apart from one another, in such a way that an electrical contact is established between the housing element (2) and the lid element (4), wherein the housing element (2) comprises a circumferential rib (9), wherein the circumferential rib (9) is arranged so as to directly mechanically contact the plurality of plastic deformations (8), wherein the plurality of plastic deformations (8) are respectively arranged below the circumferential rib (9), wherein a sealing element (11) is further arranged between the housing element (2) and the lid element (4) in such a manner that the common internal space (6) is closed against an environment (10) in a fluid-tight manner, and wherein the sealing element 11) is arranged on a beveled surface (12).
