Abstract

A battery cell, in particular lithium-ion battery cell. The battery cell has a metallic housing (2), an electrode assembly (3) being received in the metallic housing (2). The metallic housing (2) has a first housing element (4), which is connected electrically to a positive pole (8) of the electrode assembly (3), and a second housing element (5), which is connected electrically to a negative pole (9) of the electrode assembly (3). The battery cell (3) also has at least one insulation element (10), which is configured for insulating the two housing elements (4, 5) from one another electrically and is arranged between the two housing elements (4, 5). The at least one insulation element (10) has at least one barrier layer (6).
