Abstract

Method for producing an electric battery cell comprising: - stacking in an interleaved manner a plurality of first sheets (1) in a first electrically conductive material and a plurality of second sheets (2) in a second electrically conductive material, wherein each first sheet (1) comprises a first tab (5) and wherein said first tabs form a first stack (7) in which said first tabs are in mutual contact; - in a first station, mutually pre-welding the first tabs (5) to each other in the first stack (7) by means of a laser beam (10) to spatially fix the first tabs (5) to each other; - subsequently, moving the first (1) and second sheets (2) interleaved from said first station to a second station; and - in the second station, welding the first stack (7) of first tabs (5) to a first electrical contact (13) to realize an electrical connection between all the first sheets (1) and the first electrical contact (12).
