Abstract
Electrical energy storage device for powering portable devices such as vehicles or consumer electronics includes barriers to minimize migration of thermal energy and propagation of combustion in the rare event that electrical energy storage cells fail, burst and ignite. A burst structure is provided to vent gas from the device in a desired direction in the event pressure within the device exceeds a maximum value. Biased vents permit gases emanating from a portable electrical energy storage cell within an electrical energy storage module to escape and isolate other electrical energy storage cells from the gases.
