A few points to note:

Lithium-ion rechargeable and lithium primary cells are quite different.

Some lithium-ion batteries do tolerate being very cold, there are quite a few variations on the theme now.

All batteries perform badly when cold, but some are much worse than others.

Good battery management circuits would know about the problem when cold. They can be charged, but the maximum rate goes down exponentially with the coldness. The problem is that many leasure batteries are Chinese and some are not so good on managing themselves.
