An immersion cooling system for a battery system includes a battery enclosure and C metal-encased, pouch-type battery cells including C metal cases, C pouch-type battery cells arranged in the C metal cases, respectively, where C is an integer greater than one, and C vents on the C metal cases, respectively. A vent gas manifold is in fluid communication with the C vents of the C metal cases and is configured to remove vent gas passing through the C vents of the C metal cases from the battery enclosure.

An immersion cooling system for a battery system includes a battery enclosure and G battery cell groups arranged in the battery enclosure. Each of the G battery cell groups include C battery cells, where G and C are integers greater than one. A plurality of dividers are arranged between each of the G battery cell groups. A gas manifold removes vent gases from each of the G battery cell groups.

A battery module includes a first pouch battery cell and a neighboring second pouch battery cell. The battery module also includes a dielectric fluid in direct contact with and in circulation over and around each of the first and second pouch cells. The battery module additionally includes an immersion barrier positioned between the first and second pouch cells and defining an opening for controlling passage of the dielectric fluid between the first and the second pouch cells. The barrier thereby facilitates localization of a thermal runaway event in the first pouch cell by minimizing transfer of high temperature gases between the first and the second pouch cells via the dielectric fluid and controls propagation of the thermal runaway event in the module. The battery module further includes an enclosure housing and retaining each of the first and second pouch cells, the dielectric fluid, and the immersion barrier.
