Summary:

Thermal batteries are used for many military applications, primarily as power sources for guided missiles (Tow, Patriot, Sidewinder, Cruise, etc.) and proximity fuzzes in ordinance Devices. Thermal batteries possess higher power and energy density than Lithium batteries, are reliable and durable and thus amenable to rugged environments. Therefore, these batteries can be used for predominantly stationary storage. The thermal batteries use a solid electrolyte that is inactive at ambient temperature and can be stored with little to no power loss for long periods (>25 years). However, the battery could be activated instantly (
