While it’s long been known that LG Chem — and it’s Michigan-based subsidiary, Compact Power Inc. — were chosen to build the cells for the Chevy Volt’s lithium-ion battery packs, up till now most of the research, refinement and production of those cells has been done in Korea.
LG Chem has been hinting for over a year that all of that battery cell production will eventually shift to the US. Today the company revealed that they’ve chosen to invest $300 million in a Holland, Michigan battery plant capable of suppling cells for more than 50,000 plug-in cars per year. The plant is expected to employ over 400 workers by 2013.
