Today was a big day for GM’s concept Chevrolet Volt. First, they announced an official partnership with A123Systems for the creation of the Volt’s batteries, then they told Reuters they had a firm production schedule that includes a 2010 sale date. If they stick to it, it will be the first plug-in electric hybrid from any major manufacturer. GM vice chairman of Global Product Development Bob Lutz announced that GM and A123Systems have agreed to co-develop battery technology for the forthcoming Chevy Volt (and other GM E-Flex vehicles) using A123’s nanophosphate battery technology.

"A123Systems is considered a forerunner in the development of nanophosphate-based cell technology, which, compared to other lithium-ion battery chemistries, provides higher power output, longer life and safer operations over the life of the battery."

This does not necessarily mean that LG Chem is out of the running to supply batteries for the Volt or other GM vehicles. The press release from GM notes that both A123Systems and LG Chem are potential suppliers for E-Flex vehicles. "A123Systems and LG Chem are both top-tier battery suppliers, with proven technologies," said Denise Gray, director of GM’s Energy Storage Devices and Strategies. "We’re confident one, or possibly both of these companies’ solutions will meet our battery requirements for the E-Flex system." But the close cooperation between GM and A123 for the development of batteries specifically for GM’s needs makes it more likely that A123Systems will end up as the major supplier for the final product.

Development of these batteries will, of course, have implications in fields other than just plug-in/hybrid vehicles. Presently, much of A123Systems’ battery production is used for power tools. But ongoing developments in battery technology will have ramifications for all kinds of devices that use portable power from cordless tools to laptop computers and other portable electronics.

After the press conference Reuters caught Lutz, and asked him more specifically about the Volt’s time line. Lutz replied "We’ll have some on the road for testing next spring, and we should have the Volt in production by the end of 2010." That’s the firmest language we’ve yet heard, and the only date currently set by any manufacturer for a plug-in hybrd.
