Battery thermal switch

describes a battery having a housing, at least one single cell with at least one positive and at least one negative electrode, which is disposed in the housing, a positive Abgriffspol which is connected a positive electrode with the least and a negative Abgriffspol, at least with the a negative electrode is connected, and a method for the safe operation of such a battery. The battery is characterized particularly by the fact that it comprises at least one thermal switch which in consequence of a temperature-induced expansion and / or deformation changes its circuit state with a temperature rise inside the housing over a temperature threshold beyond and thereby triggers a safety mechanism that prevents a further rise in temperature.
