Ultium Cells invests $2.3B to upgrade battery manufacturing facility in Tennessee 

July 22, 2025
The upgraded facility will produce low-cost lithium iron phosphate battery cells by late 2027. 

Ultium Cells, a joint venture between General Motors and LG Energy Solution, has announced plans to upgrade its battery cell manufacturing facility in Spring Hill, Tennessee. The company, which produces lithium-ion battery cells for electric vehicles, is investing $2.3 billion into the project and currently employs approximately 1,300 people. 

The upgrade will convert existing battery cell lines at the Spring Hill facility to manufacture lithium iron phosphate (LFP) battery cells, with commercial production expected to begin by late 2027. The company aims to scale production of lower-cost LFP technologies to complement its high-nickel and future lithium manganese-rich offerings. The project will support expanded battery chemistry capabilities at the facility, increasing affordability and consumer choice in the EV market. The upgraded facility will also benefit from GM’s flexible EV platform, designed to integrate multiple battery chemistries and form factors.

What people are saying

In a recent quote, Kee Eun, President and CEO, Ultium Cells, said, “We are grateful for the continued partnership and support we've received from the State of Tennessee as we continue to advance our lead in EV battery cell manufacturing. This investment expands our capabilities beyond a single battery cell chemistry, allowing us to produce new chemistries alongside our existing cells. Expanding our product portfolio ensures Ultium Cells will remain at the forefront of battery cell innovation and sustain our commitment to be a stable, long-term employer for the communities we serve.” 

TNECD Commissioner Stuart C. McWhorter, added, “Ultium Cells’ additional investment and commitment to innovating and enhancing its Spring Hill operations is a testament to the state’s longstanding, cohesive partnerships, which started with General Motors, and grew to include LG Energy Solution in 2021, and we stand ready to continue supporting these companies and their joint venture for years to come.”
