>One could equally argue that the fact we don't have a million mile battery already suggests that there may be intractible problems to solve.
That would be a good argument if batteries had been stuck for decades at a much lower limit. But the fact is their lifetime has been steadily increasing, and will reach a million miles within a few years at most.
