Thionyl chloride from batteries

I searched for this on here but couldn't find any posts so don't yell at me for not using the search
Apparently there are lithium batteries that are mainly used in industry with an anode of lithium (which is pretty useful by itself) and a thionyl chloride electrolyte, in a paste with graphite I think.
Could these be any use for their thionyl chloride? They're only used in industry but surely they couldn't be that hard to find. They could perhaps be cracked open under a solvent (benzene or CCl4?) the lithium pulled out and stored for later use and then just stirred up to get the paste out and filtered to remove the graphite and casing. The solvent could then be distilled off or the mix could be used for chlorinations as is. Surely it isn't the cheapest way to get thionyl chloride but seeing as people are opening up energizer batteries just for the lithium, some extra thionyl chloride could be useful too. Plus they make these things up to pretty big sizes.
