ABSTRACT:
Enhanced safety is provided in the event of an information handling system catastrophic battery failure by extending a flame container outward from the battery to vent flammable gases through holes having a quenching distance that retards transfer of flames from the battery. For example, telescoping cylinder sections disposed proximate the casing of a battery cell are forced outward as a telescoping assembly when pressure within the casing exceeds a predetermined safety threshold. The flame container vents flammable gases away from other cells of the battery and may direct the vented gases to the exterior of an information handling system housing or to the interior of the housing.
