Abstract
A battery packaging assembly having safety features that reduce the risk of thermal propagation is disclosed. The battery packaging assembly may include a foam layer having a plurality of cutout trenches, the foam layer configured to engage battery cells in a press-fit relationship. In addition, the battery packaging assembly may include a tray configured to receive the foam layer, the tray enclosing a compartment configured for receiving a plurality of battery cells. Further, the battery packaging assembly may include a ventilation cavity in fluid communication with the plurality of trenches of the foam layer.
