A battery module includes first and second neighboring battery cells. The battery module also includes a cold-plate configured to remove thermal energy from the first and second battery cells. The cold-plate includes first and second sections configured to seat respective first and second cells. The first section defines a first vent arranged directly adjacent the first cell and configured to exhaust gases therefrom. The cold-plate additionally includes a first closure element arranged within and configured to block the first vent in a first mode to transfer thermal energy from the first cell to the cold-plate. The first closure element is additionally configured to open the first vent in a second mode when the first cell undergoes a thermal event to exhaust gases and transfer thermal energy from the first cell through the first vent and thereby control propagation of a thermal runaway in the battery module.
