Abstract

The present invention relates to a method (S) for assembling a stack (10) of prismatic battery cells (11, 12, 13, 14), a stack (10), a battery module (30) and a vehicle including at least one battery module (30). The method (S) is carried out on a production line and comprises the following steps: (S1) providing a first device unit for handling the battery cells (11); (S2) providing a second device unit for supporting a roll of a spacer foil and assembling the spacer foil to the battery cells, the spacer foil being self-adhesive and having a thickness of 300 µm to 550 µm; and (S3) adhering spacer stripes (24, 25) from the roll on both longitudinal sides (17, 18) of each battery cell (11), wherein the spacer stripe (24, 25) is adapted such that a central portion (17', 18') of the respective longitudinal side (17, 18) remains uncovered.
