Surging oil prices are boosting demand for fuel-efficient cars and trucks, intensifying competition for new technology. The U.S. Energy Department said last week it plans a $30 million program funding the development of plug-in electric vehicles, while Toyota Motor Corp., the world's largest maker of hybrid cars, said June 11 it plans to start mass-producing lithium-ion batteries in 2010.
Lithium-ion batteries, used to power mobile phones and laptop computers, are lighter and more powerful than the nickel- hydride units currently used in hybrid vehicles.
Hybrid cars use an electric motor for low-speed power, and a conventional gasoline engine that takes over as the car accelerates.
