Abstract

A battery module includes a cell stack including a plurality of battery cells stacked in a direction, a module housing having an internal space in which the cell stack is received and an air inlet and an air outlet through which air enters and exits, a valve installation hole formed through a side wall of the module housing, a feed valve nozzle installed at the valve installation hole facing the internal space of the module housing, and a water expandable member provided in the module housing. The water expandable member expands in volume when it absorbs water during operation of the feed valve nozzle to close at least one of the air inlet, the air outlet or the valve installation hole.
