SPRING HILL, TN—Ultium Cells LLC, the joint venture between General Motors and LG Energy Solution, announced plans to upgrade its battery cell manufacturing facility in Spring Hill, Tennessee, to begin producing lithium iron phosphate (LFP) battery cells. The transition will begin later this year, with commercial production expected by late 2027.
The upgrade builds on a $2.3 billion investment announced in 2021 and reflects GM’s broader strategy to lower EV costs while expanding battery options for consumers. LFP cells offer a more affordable alternative to nickel-based batteries and are becoming increasingly popular among U.S. automakers.
“At GM, we’re innovating battery technology to deliver the best mix of range, performance, and affordability to our EV customers,” said Kurt Kelty, GM’s vice president of batteries, propulsion, and sustainability. “This upgrade at Spring Hill will enable us to scale production of lower-cost LFP cell technologies in the U.S., complementing our high-nickel and future lithium manganese-rich solutions.”
The Spring Hill facility currently produces nickel cobalt manganese aluminum (NCMA) cells, primarily for GM’s Cadillac Lyriq and other EVs assembled nearby. That work will continue at GM’s Ultium Cells plant in Warren, Ohio. The addition of LFP production will allow Spring Hill to manufacture multiple battery chemistries under one roof.
The facility employs approximately 1,300 workers, who earlier this year ratified their first contract with the United Auto Workers. The upgrade also drew praise from Tennessee state officials, who called it a win for local job growth and U.S. battery leadership.
Ultium Cells supplies battery cells for GM’s growing EV lineup and plans to support additional industries, including rail, aerospace, heavy trucking, and marine transportation.
