LG Chem
The Volt's battery cells are produced by LG Chem in South Korea and then shipped to the US, where the battery packs are assembled at a purpose-built facility in Brownstown Charter Township, Michigan owned and operated by General Motors. Compact Power, the North American subsidiary of LG Chem, is building a battery plant in Holland, Michigan to manufacture the advanced battery cells for the Volt and other carmakers, with capacity to produce enough cells for 50,000 to 200,000 battery packs per year. The million Holland plant was funded by 50% U.S. Department of Energy matching stimulus funds and is planned to open by mid-2012.
