SELECTIVELY GAS PERMEABLE VENT FOR A BATTERY CELL
DRIVE
April 23, 2026
A battery cell includes an enclosure including a plurality of walls that define a cell stack receiving zone, a one-way valve mounted to the enclosure on one of the plurality of walls and fluidically connected to the cell stack receiving zone. The one-way valve includes an inlet mounted to the one of the plurality of walls, an outlet, and a valve member that selectively connects the inlet and the outlet to vent the cell stack receiving zone. A gas permeable membrane is arranged between the cell stack receiving zone of the enclosure and the outlet of the one-way valve. The gas permeable membrane allows selected gases to flow from the cell stack receiving zone through the outlet while preventing substances from passing through the outlet into the cell stack receiving zone.
