Abstract: A cell separating element for arrangement between two battery cells of a cell stack, the cell separating element is elastically compressible at least in a first direction and includes at least one fire protection layer. The cell separating element includes a flexible outer shell enclosing an interior space in which a fluid is located, the at least one fire protection layer is arranged in the interior space and comprises an intumescent material.

Abstract: A battery cell which has a cell housing which encloses a cell interior. The cell housing has a first housing side in which a releasable cell degassing opening is arranged, and which includes an electrode layer arrangement arranged in the cell interior, and an insulation element made of an electrically insulating material arranged between the electrode layer arrangement and the first housing side in the cell interior. The insulation element has a bursting area which is directly opposite to the releasable cell degassing opening.

Abstract: A prismatic battery cell including a cell housing made of a first material. The cell housing includes a first cell wall with a releasable cell degassing opening. The battery cell includes a heat protection element with a base element which is formed from a second material which has a higher melting point than the first material, and which has two opposing side tabs and a base plate which connects these via a respective protective edge and has a through-opening. The base plate is arranged flat against the first cell wall or is integrated into the first cell wall so that the through-opening overlaps with the releasable cell degassing opening, and the respective first and second protective edges overlap with at least part of the respective first and second edges or are integrated into them.

Abstract: A support structure for a motor vehicle includes at least two A pillars, a front wall and a front wall cross beam which is designed as a hollow profile and whose ends are connected to the respectively assigned A pillar. The connection of the front wall cross beam end is established by a torsionally rigid rooting in the A pillar.
