Though I doubt anyone would try anyway, let me caution you never to
open a lithium thionyl chloride battery.  Nasty chemicals inside.  For
messing with by knowledgeable people in a chemistry fume hood only.
Not like sweet, innocent zinc-acid batteries.

By sucking I mean they have a high internal resistance, which causes the battery to internally absorb as much power as it is putting into the load during peak current conditions.

But man they put out a lot of energy. It is these properties that make lithium chemistry batteries so attractive but at least with the current examples once you set up lithium chemistry batteries to be rechargeable you loose the low internal resistance.
