Abstract: A battery cell including a battery cell casing having a rupture membrane, an electrode unit disposed in the battery cell casing, and an ignitable material that is disposed in a region of the rupture membrane and is configured to ignite and thereby open the rupture membrane on overheating of the battery cell casing and/or of the battery cell is provided. A battery module including a plurality of battery cells is further provided.

Abstract: A cell module for an electrical energy store of a motor vehicle includes at least two cell packs that are connected together and each have a plurality of interconnected storage cells, a cell module frame having at least two frame portions arranged adjacent to one another each for receiving one cell pack, a cover arranged on the cell module frame for covering the frame portions, and at least one heat-resistant firewall-type barrier arranged on the cover to overlap a transition between the two cell packs. The barrier is designed to divide a space adjacent to the cover into at least two fire compartments in order to prevent hot gas of a cell pack that is flowing into the space from spreading to an adjacent cell pack.

Abstract: The invention relates to a battery device (10) for a motor vehicle, having a plurality of battery cells (12) which are accommodated in a housing and rest at least against a heat-conducting potting compound (20) or a heat-conducting pad, which potting compound or pad rests against at least one structural component (22) of the battery device (10), as a result of which heat (14) can be dissipated from the battery cells (12) to the structural component (22) via the heat-conducting potting compound (20) or the heat-conducting pad.
