Why aren't there 1.5v AA rechargeable batteries?

classic rechargeable batteries are always 1.2V. That's due to the chemistry.
The "low power" warning is the reason why a lot of devices will tell you not to use rechargeable batteries, as they will trigger the low battery warning earlier, and the cutoff voltage might be reached earlier.
I think there are modern rechargable lithium batteries with usb ports that will emulate 1.5V batteries and their voltage curve. But they have their own quirks as well
Those USB charging batteries scare the lights from me. I saw one explode once. Not a nice thing.
