Not something I've ever seen in the real world, and they don't exist now which means they are old (probably discontinued for a reason) and irrelevant to the discussion. You are best case scenario selectively comparing things to suite your preconceived notions, none of what you are saying reflects reality. If you are after a specific energy density figure you can't compare a AA Li-ion battery to AA Ni-MH battery or a Li-ion AA battery to a Li-ion cell. Nobody makes rechargeable AA Li-ion batteries aside from weird Chinese shit you see on Amazon, those form factors are obsolete for performance applications. Compare modern Li-ion cells to modern Ni-MH (which has pretty much stagnated) cells on power to volume and weight metric not whatever old stuff you have laying around the house.
Bellow is take from
https://www.epectec.com, they have the best consolidated statics on different batteries that I could find, it lines up with all the other research else I've looked at and aligns with my real world anecdotal experience.

Ultimately we'll just have to wait and see. Typically when the industry makes a big pivot being last to party is not a good thing.
Looking at the last 10 years of their product development hasn't been particularly impressive or inspiring for the future either. They needed BMW to build them a new Supra cause apparently didn't have the talent or enough money to do it themselves. The 86 is co-developed with Subaru which is fine but it would be nice to know they can build a high performance car without relying one someone's technology. The Tundra, Sequoia and and Landcruiser used the same platform and drivetrain for like 10+ years and while the Landcruiser is very capable off road (its also very expensive) its unremarkable otherwise the other two only sell because of "
Toyota reliability" which is real thing but at some point becomes moot if you aren't producing competitive products.
That and they usually let their products do the talking but lately it seems like they making a lot of noise about their future EV line but not showing much to back it up, feels kinda desperate. At least when Tesla announces something its either exciting, or absurdly funny, Toyota's vapoware EV line up is the most boring thing I've ever seen. The one EV they'll have for 2023, the bZ4X looks basically like a VW ID.4 2-3 years late. Maybe they have more in pipeline and they just aren't showing their cards but either way they have a lot of catching up to do.
