Primary Battery Feedthroughs

Product Description

Independent power supply for electronic devices in the industrial sector and safety engineering is often provided using special lithium-thionyl chloride (Li-SOCl2) batteries, which enable electrical devices to be supplied with high-current pulses.

Lithium-thionyl chloride batteries are frequently used in applications with extreme environments, often involving highly demanding temperature profiles. In order to protect these sensitive batteries from such harsh conditions, they are encapsulated in hermetically sealed primary battery feedthroughs designed for conducting high voltages.


Lithium and thionyl chloride are extremely aggressive substances. However, batteries can be protected over long periods using special types of glass and metal that are highly resistant to both corrosion and chemicals. The glass-to-metal sealed feedthroughs creat a hermetic seal and support efficient power conductivity.


Lithium-thionyl chloride batteries are used in many emergency and safety-critical applications, alarm systems, real-time clocks, meteorology, radio communications and global positioning systems (GPS).

Technical Details


Glass-to-metal sealing is used to create a reliable hermetic seal for Li-SOCl2 battery feedthroughs. In addition, the materials used in these housings are extremely corrosion-resistant. Please click on this page for more information.
