What are the advantages of lithium thionyl chloride batteries?

The advantage of a lithium thionyl chloride battery is the high density available in a small package. With a long-shelf life this intrinsically safe battery is available in numerous design configurations.

Are lithium thionyl chloride batteries rechargeable?

Lithium thionyl chloride (Li-SOCl2) batteries are not rechargeable. They belong to the category of primary or non-rechargeable batteries. This means that once they have been fully discharged, they cannot be recharged and reused.
