DETROIT --- General Motors Corp. said it will invest $30 million in a U.S. plant that will build next-generation batteries for its all-electric Chevrolet Volt, Reuters reported.
The facility is set to open in Michigan in 2010. The plant will assemble lithium-ion battery cells manufactured by South Korea's LG Chem Ltd. into 400-pound packs. These packs will power the Volt plug-in car.
