Short title	One hot cell heats neighbours, releasing gases that accumulate and can ignite or explode.
Image title	A sealed battery pack with four cells stands on the floor of a confined space. The initial hot cell heats the adjacent cells, which heat to different degrees. Gases vent from the hot cell and accumulate as a flammable gas layer under the ceiling. Water sprayed at the pack is deflected by the sealed casing. An ignition source near the gas layer can later cause a flare or explosion, shown in a separate branch. A note gives the thermal runaway onset as 70 to 250 °C depending on battery type.
