BATTERY SYSTEMS WITH POUCH CELLS

Battery systems are provided that include polymer cells/pouch cells. The polymer cells/pouch cells are structured such that, in response to an increase in pressure within the polymer/pouch cell, e.g., a pressure increase beyond a threshold level, the polymer/pouch releases gasses in a directionally...

Beschreibung
Zusammenfassung:	Battery systems are provided that include polymer cells/pouch cells. The polymer cells/pouch cells are structured such that, in response to an increase in pressure within the polymer/pouch cell, e.g., a pressure increase beyond a threshold level, the polymer/pouch releases gasses in a directionally controlled manner so as to facilitate withdrawal of the gasses from the battery enclosure through a vent structure that is positioned for ease of communication with the released gasses. The battery enclosure is generally sealed, e.g., hermetically sealed, and the polymer cells/pouch cells may be spaced from each other, e.g., by a support structure that may include interleaved barrier structures.
