Not a freezer: liquid nitrogen.  Apparently, this is actually one way that 
*damaged* Li batteries are (or have been) recycled: freeze them with liquid 
nitrogen to render them inert, then put them into a huge shredder.

It is not one of the ways mentioned in this paper, so perhaps it is no longer 
in use, or was never in widespread use?
