Researchers predict a new type of lithium battery under development could give an electric car enough juice to travel a whopping 800 kilometers before it needs to be plugged in again--about 10 times the energy that today's lithium ion batteries supply. It is a tantalizing prospect --a lighter, longer-lasting, air-breathing power source for the next generation of vehicles--if only someone could build a working model. Several roadblocks stand between these lithium–air batteries and the open road, however, primarily in finding electrodes and electrolytes that are stable enough for rechargeable battery chemistry.

A map of all the country's charging stations shows the easiest places to own an EV, and the places where no one seems to care. For electric cars to bloom, there needs to be a place to plug them in.

To press the "accelerator" on a Tesla Roadster 2.5 is to get an intimation of life as a race car driver. In perhaps the signature display of an electric car's appeal to gearheads, the Roadster instantly applies more than 300 amps of electric current to deliver 288 horsepower worth of acceleration--it's called instant torque, 273 pound-feet of it to be specific, and it's something that fossil fuel engines cannot provide due to the demands of combustion. That allows even an unprofessional driver to go from 0 to 100 kilometers per hour in seconds
