Abstract

The invention relates to a battery cell (2), in particular a prismatic lithium ion cell, the battery cell (2) comprising an electrode assembly (4), a battery case (6) for housing the electrode assembly (4) and a cap assembly (S) for closing the battery case (6), the cap assembly (S) comprising a set of terminals (10) arranged thereon, wherein the electrode assembly (4) comprises first electrode plates (14), separator plates and second electrode plates (16) stacked on one another, wherein electrode tabs (12) are provided to electrically connect the electrode assembly (4) with the terminals (10). The electrode tabs (12) are bent at least once in a direction normal to the first and second electrode plates (14, 6). Furthermore, the invention relates to a method of manufacturing a battery cell (2).
