Lutz says a Volt battery supplier selected, won't say who

At a preview of GM's 2009 model year lineup yesterday in Jolliet IL, Bob Lutz revealed that the production supplier for the Chevy Volt battery has been selected. Unfortunately, the GM Vice Chairman would not say which of the development suppliers had been selected. Two partnerships have been supplying prototype batteries to GM for the E-Flex program since late in 2007. LG Chem and its U.S. subsidiary Compact Power Inc have long been considered to be the leaders in the race to supply the most critical component of the Volt.
Continental and A123 have also been providing batteries but they ran behind CPI in initial pack deliveries. Lutz reiterated that a test fleet of production-intent Volts would be on the road being field tested by late 2009 ahead of a November 2010 retail launch.
