Thermal Battery Covers

Thermal batteries are inert batteries designed for absolute reliability and shelf storage. Thermally activated (“thermal”) batteries are primary batteries that use molten salts as electrolytes and employ an internal pyrotechnic (heat) source to bring the battery stack to operating temperatures. Often used in demanding military applications involving challenging environmental conditions, these batteries must be reliably sealed to ensure its optimal performance.

SCHOTT utilizes a mix of carefully selected glass and metal materials, based upon our years of experience with sealing technology for critical applications, to provide protection for these batteries. Although lithium and thionyl chloride are extremely aggressive substances, the batteries can be reliably encapsulated over long periods of time due to our highly corrosion- and chemical-resistant materials used. These glass-to-metal sealed feedthroughs ensure that the batteries are hermetically sealed and that power is conducted efficiently.
