ABSTRACT:
A method and apparatus is provided in which a layer of an intumescent material surrounds the casing of a battery, the layer helping to prevent the formation of perforations in the battery casing during a thermal runaway event and, if a perforation is formed, inhibiting the flow of hot, pressurized gas from within the battery. A sleeve, surrounding the cell, may be used to contain the intumescent material during the thermal event.
