No.

There are half-a-dozen rechargeable lithium technologies, a few of
which are available in AA sized cells, and each one needs a particular
charger. At present they're so different that you might as well get a
new charger, from the same supplier, with each batch of cells. The
cell voltage is also such that they're incompatible with AA cells.

There are also some lithium technologies that are resolutely primary.
Trying to recharge these is likely to start a fire. These are the more
common forms in AA format.

If you had lithiums that were safe to put near a charger, I think
you'd already know.
