You can buy an AA size protected LiIon today.  $8.00

I like them, but resisted using them.  I think my wife (or myself) will probably get them mixed up and try to stuff two of them into something that expects two 2x1.2V and be blasted with 2x3.7V.  Bye bye equipment.

Nitecore NL1485 14500 850mAh 3.7V Protected Lithium Ion (Li-ion).  I consider Nitecore a reputable brand, but that is an untested opinion only.

Rather than Nitecore, just go straight for Sanyo/Panasonic UR14500P 840mAh cell, red one at below photo, bought it while ago together with with my new Lumintop EDC05 AA sized flashlight, capable of using Alkaline/NiMh or Li-Ion cell (with twice the brightness) and won't over discharge either types.

I have some Sanyo 1650mAH NiMH from 1999 (before Eneloop) that can still be used.  I gave them to my son once I had enough Eneloops and he uses in his Lego motor power box.  Some of my Eneloops are 1 years old now and still going.

We have a Dust Buster from the mid 80s at our cabin that still has the original NiCd batteries in it. It doesn't run very long but remarkably it does still work.
