I may be wrong & am definitely no expert in battery life management but :

Considering they have to be kept above a minimal charge level AND knowing they wear out depending on the number of charge cycles, I'd still say it's beneficial to store them cold.

Although this won't hurt anything, Lithium Ion batteries are different
then NiCad batteries, so they don't benefit from being stored in such a
cold place. Shallow charges are good, and they should be topped off
before going into storage. Heat should also be avoided, but like I said,
refrigeration isn't beneficial.
