Method for producing an electrically conductive connection, in particular between a contact pin (30, 32) and a cross connection link (34) on battery cells (10) in a battery pack (12). The contact pins (30, 32) are produced from a material A and the cross connection links (34) are produced from a material B, which is different than material A. The contact pins (30) and (32) can also be produced from the material B and the lug-shaped cross connection links (34) can also be produced from material A. Openings (35) or slot-shaped opening geometries (72) are produced in the cross connection link (34). A cohesive connection (52) between the contact pins (30, 32) and the lug-shaped cross connection links (34) is produced by laser welding.
