A thermal propagation prevention device and method for a battery pack including a plurality of battery cells. The device includes a liquid loaded material, such as a hydrogel or liquid loaded superabsorbent polymer, contained in a propagation arrestor configured to cover at Least one of the plurality of battery cells. The liquid loaded material is configured to phase change under heat from a rupture of the at least one of the plurality of battery cells and release a quenching vapor. The vapor further dilutes the electrolyte released from the at least one of the plurality of battery cells.
