摘要： The present invention discloses an electrochemical cell design that safely discharges after cell venting. The cell includes a housing and a lid assembly connected to the housing via a vent. The housing houses an electrode assembly with a first electrode separated from a second electrode by a separator. The first electrode is electrically connected to the housing, and the second electrode is electrically connected to the lid assembly structure. The cell has a non-venting configuration characterized by the vent connecting the lid assembly to the housing such that the internal pressure is maintained at a pressure above atmospheric pressure. A venting configuration is characterized by (A) the vent releasing the housing from the lid assembly when a predetermined internal pressure is exceeded; (B) venting the internal pressure; and (C) the venting dislodging the lid assembly such that it makes electrical contact with the housing, thus discharging the cell.

摘要： A pressure equalization device for a housing has a base body and a closure element with a flow path between them being open in a normal operating state of the pressure equalization device. A flow opening in the flow path is spanned by a membrane. An emergency venting spike projects from the closure element toward the membrane. The pressure equalization device transitions after emergency venting into an emergency operating state in which the closure element gas-tightly closes the base body. A housing with such a pressure equalization device is provided. In a method for pressure equalization with such a pressure equalization device between a housing interior and an environment, gas exchange between interior and environment is performed through the membrane and the flow path between closure element and base body. During emergency venting, the membrane is destroyed by the emergency venting spike. The closure element then closes the base body.
