SAFETY DEVICE FOR ARRANGEMENT IN A BATTERY CELL OF A LITHIUM-ION BATTERY, LITHIUM-ION BATTERY CELL WITH SAFETY DEVICE

摘要

A safety device for arrangement in a battery cell of a lithium-ion battery includes at least one metallic conductor configured in a planar form, in particular a metal plate or a metal foil. The conductor includes an insulating layer applied thereon and a terminal contact configured for the electrical connection to a terminal of the battery cell. The conductor has at least one heating resistor with a first contact and a second contact arranged on the insulating layer so as to enable an electric current to be passed through the heating resistor by way of the contacts. A battery module with a control device includes at least one lithium-ion battery cell with the safety device.
