GM is partnering with LG Energy Solution to upgrade its Ultium battery factory in Tennessee to produce lithium-iron-phosphate cells for low-cost EVs.
The move challenges China's LFP monopoly as most LFP cells are currently made in China despite being invented and commercialized in the U.S.
GM is diversifying its battery sourcing strategy: using NMC for long-range models, developing a new LMR chemistry, and switching to LFP for entry-level vehicles.
The upgraded battery factory is expected to start commercial production of LFP cells by late 2027, providing a cost-effective and safe option for GM's EV range.
