What's the biggest problem with electric cars? Sure, some would say it's that they're too quiet, making them a danger to pedestrians, but that's been solved by a simple technology called Baseball Cards in the Spokes (or something like that). The real biggest problem is battery technology. But one company is testing a new formulation of lithium-ion batteries, using nanotechnology, which may offer e-cars a longer range and charging times acceptable to those who don't have all day to spare. Could they be the answer to the electric-car conundrum?
