Alec,
 There *are* some newer battery technologies that are 'promising', but some 
are very costly, making their use in an EV unfeasable. It's often a case of 
their using exotic materials, not just low production rates, that make them 
so expensive
Once again, they must compete against a technology that takes a couple of 
hundred pounds of common, inexpensive materials, with a very few man-hours of 
labor, to make a device capable of 100+ HP. It is fed by an energy source 
that's found in great abundance, is easy to transport, and has very high 
density.
If we were all driving EV's right now, and someone invented the modern IC 
engine and put it in a car, I think we'd see it take over the market 
overnight. :-)
