Abstract:

This invention pertains to thermal battery activated by external heat comprising an anode, e.g. composed of a lithium-aluminum alloy, a cathode, e.g. composed of iron disulfide, and an electrolyte, e.g. a lithium chloride-potassium chloride eutectic, the electrolyte being inactive at ambient temperature but being activated by melting at a predetermined temperature when exposed to external heating. The battery can be used as a sensor or to ignite pyrotechnic and power electronic devices, in system for reducing the hazard of ordnance exposed to detrimental heating. A particular application is the use of the battery to activate a squib to function in conjunction with one or more other components, to vent an ordnance case, preventing its explosion in a fire.
