PRESSURE RELIEF ELEMENT, PRESSURE RELIEF DEVICE AND BATTERY |
| 摘要 |
The present invention relates to a pressure relief element (11) to be used as an overpressure safety means in devices where a gaseous medium must be rapidly released in case of overpressure, wherein the pressure relief element (11) has at least one notch (9) which is designed as a predetermined breaking point where the pressure relief element (11) breaks at a certain level of overpressure, thereby irreversibly opening an exhaust path for the gaseous medium. The present invention also relates to a pressure relief device of an electrochemical battery, comprising such a pressure relief element and a battery comprising such a pressure relief device. |
