Batteries Still the Issue in Quest for Electric Cars
Clever and attractive, the Chevrolet Volt, a design study for a new wrinkle in electric cars, dominated the headlines coming from the Detroit auto show in January. But the introduction was punctuated with an asterisk.
The car that promised a fuel economy equivalent of 150 miles a gallon and a range of 640 miles using its onboard recharging system carried a major caveat: the lithium-ion batteries required to make it a reality are not yet available, and won't be until 2010 at the earliest, industry experts say.
The Volt is not the only car waiting for lithium-ion batteries to be roadworthy. Reports last month in Nikkan Kogyo Shimbun, a Japanese business newspaper, said the next generation of the Toyota Prius would be delayed by six months because the carmaker had decided that lithium-ion batteries were not quite ready.
