METHOD FOR PRODUCING A BATTERY CELL AND BATTERY CELL

摘要

A method for producing a battery cell (8) wherein, after the metallic bottom part (16) has been joined materially to the metallic wall part (14) and the second electrode side (28) has been joined materially to the feedthrough bushing (32), a metallic cover part (12) is joined materially to the metallic wall part (14), and wherein the material joining of the metallic bottom part (16) to the metallic wall part takes place only after the material joining of the first electrode side (26) of the battery roll (24) to the metallic bottom part (16).

1. A method for producing a battery cell (8), comprising a housing (10) and a battery roll (24) arranged in the housing (10), wherein the battery roll (24) has a first electrode side (26) and a second electrode side (28), the method comprising the following steps:
joining the first electrode side (26) of the battery roll (24) materially to a metallic bottom part (16) of the housing (10) before or after introduction of the battery roll (24) into a metallic wall part (14) of the housing (10), and joining the second electrode side (28) of the battery roll (24) materially to a feedthrough bushing (32) after the introduction of the battery roll (24) into the metallic wall part (14), wherein, after the metallic bottom part (16) has been joined materially to the metallic wall part (14) and the second electrode side (28) has been joined materially to the feedthrough bushing (32), a metallic cover part (12) is joined materially to the metallic wall part (14), and wherein the material joining of the metallic bottom part (16) to the metallic wall part (14) takes place only after the material joining of the first electrode side (26) of the battery roll (24) to the metallic bottom part (16).
