It seems like you might be looking for "1.5V Li-ion AA", which is a 14430 with a buck converter stuck on the end.
I have pretty much the opposite preference regarding charging: I'd much rather swap in a charged spare and stick the drained battery in a slot charger than charge batteries inside devices. There's no waiting that way.
