摘要: A battery cell with improved safety. The battery cell comprises two battery cell terminals which are contactable from outside of the battery cell and an electrochemical part comprising at least one positive electrode and at least one negative electrode, an electrolyte comprising at least one conductive salt and at least one solvent, and at least one separator, wherein the at least one separator becomes at least partially impermeable for ions which can be generated inside of the electrochemical part, when the at least one separator reaches a predefined temperature.
