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.
