A battery cell having a first housing element (4) which holds the electrochemical components of the battery cell (2) and has an opening (6), and a second housing element (5) which has a voltage tap (7) to be accessed from a first surface (8) of the second housing element (5), the second housing element (5) closes off the opening (6) so that a first part region (91) of a second surface (9) of the second housing element (5) is immediately adjacent the interior space (10) of the first housing element (4), and that a second part region (92) of the second surface (9) of the second housing element (5) protrudes beyond the first housing element (4), wherein the second housing element (5) comprises a sealing element (11) connected to the first surface (8) and/or to the second part region (92) of the second surface (9).
A battery module having a battery cell, wherein the battery cell has a housing, wherein the housing comprises a first housing element which holds electrochemical components of the battery cell which comprise at least an anode, a cathode, and a separator, and furthermore has an opening, wherein the housing also comprises a second housing element which has a voltage tap connected to the anode of the battery cell or the cathode of the battery cell in an electrically conductive fashion, wherein the voltage tap is furthermore arranged to be accessed from a first surface of the second housing element, wherein the second housing element furthermore closes off the opening formed in the first housing element in such a way that a first part region of a second surface of the second housing element, which is opposite the first surface, is immediately adjacent to the interior space of the first housing element, and that a second part region of the second surface of the second housing element, which is opposite the first surface, protrudes beyond the first housing element, characterized in that the second housing element comprises a sealing element connected to at least one of the first surface and the second part region of the second surface, and wherein the battery module has a battery cell holder which comprises an interior space through which a temperature-control fluid can flow, characterized in that the battery cell is held in the battery cell holder in such a way that the sealing element seals the interior space in fluid-tight fashion from the surroundings, and that the first sealing element is arranged so that temperature-control fluid can flow around it.
