Zusammenfassung:The present invention relates to a battery cell stack in which a plurality of pouch-shaped battery cells is stacked. An alignment mark is formed at the bottom of a receiving portion configured to receive an electrode assembly in each of the plurality of pouch-shaped battery cells. The plurality of pouch-shaped battery cells is stacked such that the alignment marks individually formed at the pouch-shaped battery cells completely overlap each other in a stacking direction, and the alignment mark is a reference for measuring the dimensions of the pouch-shaped battery cells. Consequently, it is possible to manufacture a battery cell stack in which the plurality of pouch-shaped battery cells is accurately aligned with each other in the stacking direction.
