Battery cell, battery system and process for manufacturing a battery cell

Abstract

The invention relates to a prismatic battery cell (10), wherein the battery cell (10) has a basic shape with two opposing flat faces (14), two opposing first narrow faces (14), and two opposing second narrow faces. The battery cell (10) has a housing that surrounds an electrochemical cell of the battery cell (10), and an insulating material (12) applied to the housing for electrical insulation of at least a part of the housing of the battery cell (10). The insulating material (12) comprises a functional material (20) for swelling compensation and / or thermal insulation, which is arranged at least in the region of one of the flat faces (14) of the battery cell (10).
