Ultium Cells, a joint venture between LG Energy Solution and General Motors, has decided to upgrade its battery cell manufacturing plant in Spring Hill, Tennessee, to produce low-cost lithium iron phosphate, or LFP, battery cells as it aims to expand its business portfolio.

According to the announcement on Tuesday, the conversion of battery cell lines at the Tennessee site will begin later this year. Commercial production is expected to begin by late 2027. The plant has been rolling out lithium-ion batteries using cathode materials, namely nickel, cobalt and manganese, to produce LFP cells.

“The upgrade reflects the continued strength of our partnership with General Motors and our shared commitment to advancing EV battery innovation,” said Suh Won-joon Suh, executive vice president and head of the Advanced Automotive Battery division at LG Energy Solution.
