Primary Battery Covers

Independent power supply for electronic devices in the industrial sector and safety engineering is often provided through the use of 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 areas with extreme environmental conditions, often involving highly demanding temperature profiles. In order to protect these comparatively sensitive batteries from such harsh conditions, the batteries are encapsulated in hermetically sealed glass-to-metal sealed feedthroughs designed for conducting high voltages.
