Race to make next gen Electric cars stalled by Battery problems
DETROIT -- When the car world gathers here Sunday for the annual North American International Auto Show, the industry will be buzzing about electric power. Auto makers from General Motors Corp. to Toyota Motor Corp. will be displaying a new breed of cars that run mainly on electricity. But there is one thing the car people won't be charged up about: batteries. For all the hoopla, nobody yet has figured out how to make a small enough battery that will hold a big enough charge for these new cars -- and not be a risk to burst into flames.
