Ultium Cells, the GM and a Korea energy company has joint venture, will retrofit its Spring Hill, Tennessee battery plant to produce cost-effective lithium iron phosphate (LFP) cells, building on its existing $2.3 billion facility investment. Production line conversions begin this year, with commercial output expected by late 2027. The move diversifies GM’s EV battery strategy, complementing its high-nickel and future lithium manganese-rich chemistries while reducing costs. GM emphasized the upgrade will enhance affordability and range options for customers, while Korea energy company highlighted the partners’ shared commitment to advancing U.S.-based battery innovation. The Spring Hill facility, currently employing 1,300 workers, will maintain its existing nickel cobalt manganese aluminum (NCMA) cell production while adding LFP capabilities as a strategic shift aimed at meeting varied EV market demands.
