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

Battery cell and method of manufacturing a battery cell

An electrochemical cell includes a prismatic cell housing including a lid plate that closes one end of the housing. The cell also includes a terminal assembly having a simple structure that is supported on the lid plate. The terminal assembly includes the lid plate, a terminal and an adhesive layer that is disposed between and secures the terminal to the lid plate. The terminal assembly includes features that allow the adhesive layer to flow in a controlled and reproducible manner over the entirety of a predetermined area without flowing beyond the predetermined area. The features result from forming a stop line in the predetermined area by applying a surface treatment to the predetermined area. The stop line delineates a desired adhesive later outer boundary and engages the adhesive so as to maintain the adhesive within the predetermined area.
