Beschreibung
Zusammenfassung:	The present invention relates to a battery cell stack in which a plurality of pouch-shaped battery cells is stacked, each of the pouch-shaped battery cells includes an alignment mark formed at the bottom of a receiving portion configured to receive an electrode assembly, wherein 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, whereby 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.
