They’re really light and last a long time, but are not rechargeable.

I think you are moving the goalposts. The batteries I linked to are consumer standard lithium chemistry batteries that people can buy off-the-shelf in drug stores and be used in smoke detectors and kitchen scales.

When I said lithium-ion I was indeed referring to secondary (rechargeable) batteries. Apologies for not making that clear.

AA and AAA Nickel-metal-hydride rechargeable batteries exist, but it doesn't seem anyone ever made a li-ion equivalent.

No we’re talking about rechargeable batteries here… disposable lithium are too expensive and wasteful for frequently used high drain devices. I love them for emergency equipment like spot trackers and emergency strobe lights

The comment you're replying to specifically said lithium-ion battery. What you linked to is a lithium metal battery. They aren't the same thing.
