Abstract

A battery housing (100) comprising: a plurality of battery cells (102), each battery cell having a vent (104) positioned to face a first side (106) of the battery housing for releasing exhaust gas during a thermal runaway event; a first compartment (108) disposed adjacent to the vents of the battery cells, the first compartment being air-filled; a second compartment (110) adjacent to the first compartment, on a side of the first compartment opposite the side facing the vents of the battery cells, and in fluid communication with the first compartment via breakable openings (112) located between the first compartment and the second compartment, wherein the second compartment comprises a phase change material (114) configured to be activated when high-velocity particles and/or high-pressure gas ejected from the battery cells break through the breakable openings, and to absorb heat and trap particles released during a thermal runaway event.
