Ni-MH batteries are much heavier, can't hold as much charge, and exhibit patterning behaviour.
They do still get used for some stuff but generally lithium batteries are thought of as superior.
There's a new cheap Chinese battery car come out, anyone seen that? Uses ferrous batteries I think. And costs half the Tesla.
Of course the energy still has to come from somewhere...
