A General Motors and LG Energy Solution battery-cell plant in northeast Ohio is set to resume production next week after being idled for about seven months as weaker consumer demand for electric vehicles cut output. Tom Gallagher, Ultium Cells' vice president of operations, said most furloughed workers will return on the 17th, with employment at the site expected to reach about 1,400 when operations restart. The Warren, Ohio, plant began mass production in August 2022, has annual capacity of more than 35 GWh and said in December 2024 that it had produced its 100 millionth EV battery cell before production was halted in January. The restart comes as GM differentiates battery strategy by site: a separate GM-LG plant in Spring Hill, Tennessee, has shifted to batteries for energy storage systems, while Samsung SDI this week acquired GM's 49.99% stake in Synergy Cells, the Indiana battery venture the companies formed in 2024. Samsung SDI plans to use the New Carlisle plant for both EV and energy storage batteries, even as it and GM continue a next-generation prismatic battery development partnership. The moves extend GM's broader pullback and reworking of EV investments after write-downs tied to the business and the expiration of the U.S. federal EV tax credit in September 2025.
