Ultium Cells will upgrade its Spring Hill, Tennessee, battery cell manufacturing facility to scale production of low-cost lithium iron phosphate battery cells, building on a $2.3 billion investment announced in 2021.

Conversion of battery cell lines at Spring Hill to produce LFP cells will begin later this year, with commercial production expected by late 2027.

Ultium Cells is a joint venture between General Motors and LG Energy Solution that mass-produces battery cells to advance the push for a zero-emissions, all-electric future. It provides battery cell capacity to support GM's North American electric vehicle assembly capacity, while supporting GM’s plans to supply other automotive companies and other industries, including rail, aerospace, heavy trucking, and marine customers. 

“At GM, we’re innovating battery technology to deliver the best mix of range, performance, and affordability to our EV customers,” said Kurt Kelty, vice president 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 U.S., complementing our high-nickel and future lithium manganese rich solutions and further diversifying our growing EV portfolio."

GM said its flexible EV platform has been architected to enable the quick integration of multiple cell chemistries and form factors. 

The Ultium Cells plant in Warren, Ohio, will continue producing cells with nickel, cobalt, manganese, aluminum chemistry, which has been key to GM delivering a range of crossovers with more than 300 miles of range on a charge. 

With LFP battery technology, GM is targeting significant battery pack cost savings compared to today’s high-nickel battery pack while increasing consumer EV choice.

“The upgrade reflects the continued strength of our partnership with General Motors and our shared commitment to advancing EV battery innovation,” said Wonjoon Suh, executive vice president and head of the Advanced Automotive Battery division at LG Energy Solution. “We will bring our extensive experience and expertise in U.S. manufacturing to the joint venture facility, further accelerating our efforts to deliver new chemistries and form factors that effectively capture the unmet needs in the EV market.”

The Spring Hill facility currently employs about 1,300 people. With the ability to manufacture battery cells in multiple cell chemistries, Spring Hill will help drive U.S. battery innovation, manufacturing, and consumer choice in the EV market.

“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,” said Kee Eun, president and CEO of Ultium Cells. “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.”
