Summary: | The invention relates to a method for producing an electrode unit for a battery cell comprising the following steps: substance-to-substance bonding of contact lugs (35, 36) of a plurality of plate-shaped segments of a first electrode (21, 22) to a strip-shaped first separator layer (18), substance-to-substance bonding of a strip-shaped second separator layer (19) to the contact lugs (35, 36) of the segments of the first electrode (21, 22) or to the first separator layer (18) such that a strip-shaped composite element (50) is produced, wherein an active material (41, 42) of the segments of the first electrode (21, 22) is surrounded by the first separator layer (18) and by the second separator layer (19), and arranging a plurality of plate-shaped segments of a second electrode (21, 22) on the composite element (50). The invention further relates to an electrode unit for a battery cell, produced by the method according to the invention. |
