Abstract

The present invention relates to a battery assembly (10), comprising a battery cell stack (12) with a plurality of battery cells (12a) with respective electrode tabs (14), wherein the battery cells (12a) are stacked and electrically interconnected via their electrode tabs (14) along a stacking direction (S), and a housing with a top and a base plate, between which the battery cell stack (12) is compressed, and structural enclosure walls (16), wherein at least one barrier element (18) is included in the battery cell stack (12) between a pair of neighbouring battery cells (12a) for dividing the battery cell stack (12) into a plurality of sealed cell modules (20a. 20b), wherein the at least one barrier element (18) comprises at least one stud element (22), which extends through an opening (16a) in a first of the structural enclosure walls (16) and is fixed to the first enclosure wall (16) by means of a counter element (22a), wherein between the at least one barrier element (18) and the first enclosure wall (16), a busbar assembly (24) is provided for electrically inter-connecting the neighbouring cell modules (12a), wherein by means of the barrier element (18), the first enclosure wall (16), the busbar assembly (24) and an insulating sealing layer (26) arranged between the busbar assembly (24) and the first enclosure wall (26), a hermetic sealing of the neighbouring cell modules (20a, 20b) is provided.
