General Motors Plans to Close Michigan Battery Plant as Lease Nears Expiration
The Brownstown plant has assembled battery packs for the Cadillac Celestiq and Chevrolet Corvette E-Ray. Its work and employees are expected to move to other GM facilities.

General Motors plans to close its Brownstown Battery Assembly Plant in Michigan as the site's lease nears expiration, moving its assembly work and employees to other company facilities.
The closure does not mark a change in GM's electric-vehicle strategy. Brownstown has assembled battery packs for the electric Cadillac Celestiq, as well as battery packs and electric drive units for the hybrid Chevrolet Corvette E-Ray.
GM is also developing new battery cells at its Warren, Michigan, battery campus. The Ancker-Johnson Battery Cell Development Center and the adjacent Wallace Battery Cell Innovation Center represent a combined $900 million investment in battery development.
That work includes lithium manganese-rich cells intended for future electric trucks and full-size SUVs. GM and LG Energy Solution plan to begin commercial U.S. production of the cells by 2028.
GM plans to transfer Brownstown's work and employees to other facilities. The receiving facilities were not specified.
