Abstract: The present invention relates to a safety valve which may be produced in a simple manner and effectively provides emergency degassing when mounted on electrochemical device housings, the safety valve including: a housing defining a cavity and having a top and a bottom portion, the surface of the bottom portion covering an opening in the electrochemical device casing, and at least one protective degassing element provided on the bottom portion and configured to provide a gas through-opening when an internal pressure and/or temperature in the electrochemical device casing exceeds a predetermined threshold; wherein the material thickness of the protective degassing element is smaller than that of the remaining bottom portion. Further disclosed are kits including said safety valve and related electrochemical devices.
