New production facilities in Tennessee and Michigan are being equipped to improve EV battery output and affordability.

General Motors is accelerating its electric vehicle strategy with major investments in U.S.-based battery development and production, expanding its capacity and capabilities across multiple chemistries.

The Ultium Cells facility in Spring Hill, TN — a joint venture between GM and LG Energy Solution — will begin production of lithium iron phosphate (LFP) battery cells by late 2027, complementing its current output of nickel cobalt manganese aluminum (NCMA) pouch cells. This move builds on a $2.3 billion investment first announced in 2021.

“LFP was an American breakthrough that’s grown in popularity as a low-cost battery solution worldwide. I’m proud that we’re bringing its benefits — and associated jobs — back to America,” said , president of GM.

With the Spring Hill plant designated as GM’s hub for LFP batteries, the company is also working to finalize a production site for lithium manganese rich (LMR) battery cells. GM aims to be the first automaker to produce LMR prismatic cells at commercial scale, which the company says is key to delivering the best mix of range, performance and affordability for EV customers.

These developments are part of GM’s strategy to support a broad range of EV models, from full-size pickups to affordable electric vehicles like the Chevrolet Bolt, by leveraging a mix of NCMA, LFP and LMR battery technologies.

Meanwhile, GM is also expanding its battery development infrastructure. The company recently completed the steel frame of its new 500,000-square-foot Ancker-Johnson Battery Cell Development Center in Warren, MI, part of a $900 million investment at its Global Technical Center. Together with the adjacent Wallace Battery Cell Innovation Center, the new facility is expected to reduce development times for new batteries by up to a year.

The Ancker-Johnson Center’s first priority will be advancing LMR cells toward production, using cutting-edge tools to validate concepts and streamline the path to manufacturing. The center will support GM’s goals of reducing battery cost, improving range and speeding up charging — key factors in expanding EV adoption.

“From securing the supply chain to advancing new chemistries and cell form factors to investing in state-of-the-art facilities,” Reuss said, “every step we’ve taken is designed to build a robust, diverse America-driven EV portfolio.”

GM also emphasized its broader commitment to a U.S.-based supply chain, highlighting recent moves to secure domestic sources of lithium and magnets to support long-term growth. With multiple battery chemistries, vertically integrated facilities and rapid development pipelines, GM says it is well-positioned to lead the industry in the transition to electric mobility.
