GM to challenge China’s LFP monopoly with upgraded battery factory

General Motors (GM) announced on Monday its collaboration with LG Energy Solution to enhance its Ultium battery factory, enabling the production of lithium-iron-phosphate (LFP) cells specifically for affordable electric vehicles (EVs). This significant upgrade is set to bolster LFP manufacturing capabilities in the United States, an area currently dominated by Chinese production despite its American origins. The $2.3 billion facility located in Spring Hill, Tennessee, operates under the Ultium Cells LLC joint venture between GM and LG Energy Solution, a branch of LG Chem. Initially established to produce lithium-ion cells featuring a nickel-manganese-cobalt chemistry, the factory commenced operations in 2024, three years post-announcement. GM plans to start transitioning its battery cell production lines to LFP technology later this year, with full-scale manufacturing anticipated by late 2027. The automotive sector has increasingly favored LFP batteries in recent times due to their cost-effectiveness and enhanced safety features. LFP chemistry utilizes raw materials that are not only more affordable but also more readily available compared to alternatives such as nickel-manganese-cobalt (NMC), and they present a lower risk of fire hazards. GM's strategy encompasses a comprehensive approach to battery sourcing for its electric vehicle lineup, which currently includes 12 models. For higher-end vehicles, the company will retain NMC batteries to ensure extended range capabilities. For instance, the Chevy Silverado EV boasts a substantial 205 kilowatt-hour NMC battery pack, enabling a remarkable 492-mile range on a single charge. In addition to NMC, GM has innovated a new battery chemistry termed lithium-manganese-rich (LMR), which significantly reduces nickel and cobalt content, substituting it with more affordable manganese sourced domestically. This advancement is expected to yield battery packs that provide greater range than LFP while remaining competitively priced. The LMR technology is projected to enter the market by 2028. For entry-level models, GM plans to pivot to LFP batteries, as discussed by Andy Oury in May to TechCrunch. Given the steady decline in battery pack costs, it is anticipated that LFP prices will soon fall below those of LMR in the upcoming years. The Spring Hill upgrades are set to initiate LFP production for commercial use by 2027.
