In Quest for Better Battery, Keep an Ion Nationalism-A123 Systems Co's Li Ion & GM

"One beneficiary of this battery war is a small Watertown, Mass., start-up called A123 Systems, which has developed a small pack of lithium-ion batteries that can be retrofitted into the spare-tire well of a Toyota Prius. The batteries turn the Prius into a "plug-in hybrid," which can be recharged through an electrical outlet and run almost exclusively on electricity in the first 40 miles of driving."

"This is the kind of technology GM wants to use, to develop, among other future vehicles, a Saturn Vue Green Line plug-in hybrid SUV and a real-world version of the Chevrolet Volt show car the company has been promoting to demonstrate its seriousness about clean technology."
