That has been the biggest problem with battery powered cars is that they only last for so long before needing a long recharge.

Well let's say this 1.5V AA cell can discharge at 2 amps (same as energizer lithium). That's 3 watts. And a car needs (say) 100kW. Then you'd need 33,000 of them to run your car. At 15g each that's about 500kg of battery to put in your car. And 33 million dollars!
