General Motors and LG Energy Solution will commercialize LMR battery technology in prismatic battery cells for GM electric trucks and full-size SUVs. This initiative builds on their partnership to develop prismatic cell design and manganese-rich chemistries. GM plans to become the first automaker to use LMR battery technology in EVs.
Ultium Cells, a joint venture between GM and LG Energy Solution, will begin commercial production of LMR prismatic cells in the U.S. by 2028, following pre-production in late 2027. GM will validate the final production design at its Battery Cell Development Center in Warren, Michigan, and LG’s battery facility.
LMR Battery Technology Offers Cost and Range Benefits
Battery cathodes use cobalt, nickel, and manganese—cobalt being the most expensive. GM and LG developed LMR battery cells with more manganese, reducing cost while increasing energy density. Its new prismatic cell delivers 33% more energy density than lithium iron phosphate (LFP) cells, without raising costs.
GM’s current high-nickel chemistry already leads its electric truck platform in range. GM said it expects to offer over 400 miles of range while lowering battery pack costs.
GM and LG Set Industry Standard in Battery Innovation
“We’re pioneering manganese-rich battery technology to unlock premium range and performance at an affordable cost, especially in electric trucks,” said Kurt Kelty, VP of battery, propulsion, and sustainability at GM. “LMR will complement our high-nickel and iron-phosphate solutions to expand customer choice in the truck and full-size SUV markets, advance American battery innovation, and create jobs well into the future.”
“We’re excited to introduce the first-ever LMR prismatic cells for EVs. It’s the culmination of our decades-long research and investment in the technology,” said Wonjoon Suh, executive VP and head of the Advanced Automotive Battery division at LG Energy Solution. “GM’s future trucks powered by this new chemistry are a strong example of our commitment to offering diverse EV options.”
LMR Battery Technology Research and Manufacturing Drive Breakthroughs
GM began researching manganese-rich lithium-ion batteries in 2015. Its engineers prototyped LMR cells at the Wallace Battery Cell Innovation Center. LG holds over 200 patents in LMR chemistry, making it a global leader.
GM Strengthens Battery Supply Chain
GM will incorporate LMR battery cells into its domestic supply chain and manufacturing systems. This strategy supports U.S. battery production. It sources lithium, graphite, and manganese from North America to align with its long-term electrification goals.
