Ultium Cells, the battery manufacturing joint venture between General Motors and LG Energy Solution, will retrofit its Spring Hill, Tennessee facility to support the production of lithium iron phosphate (LFP) battery cells.
This strategic upgrade follows a $2.3 billion investment announced in 2021, with line conversions beginning later this year and full commercial output anticipated by late 2027.
“At GM, we’re innovating battery technology to deliver the best mix of range, performance, and affordability to our EV customers,” said Kurt Kelty, VP of batteries, propulsion, and sustainability at GM. “This upgrade at Spring Hill will enable us to scale production of lower-cost LFP cell technologies in the US, complementing our high-nickel and future lithium manganese rich solutions and further diversifying our growing EV portfolio.”
Designed with chemistry flexibility in mind, GM’s Ultium platform will continue to accommodate multiple cell formats and technologies. Its Warren, Ohio plant remains focused on nickel cobalt manganese aluminum (NCMA) production – a key component in delivering crossovers with over 300 miles of range. The integration of LFP cells at Spring Hill is expected to deliver meaningful cost reductions at the pack level while expanding consumer choice.
Spring Hill currently employs roughly 1,300 staff and is positioned to play a central role in domestic battery innovation. With multi-chemistry capability, the site supports US manufacturing competitiveness and EV market diversification.
