Thermal batteries are single-use, hermetically sealed electrochemical power sources that remain inert until activated by a pyrotechnic heat source, covering cells based on lithium-alloy anodes, molten-salt electrolytes such as LiCl–KCl eutectic, and iron disulfide or lithium cobalt cathodes, used across missile guidance, fuzing, and ejection-seat systems.
