GM and LG Energy Solution Announce Breakthrough in Manganese-Rich Battery Tech for Electric Trucks

General Motors and LG Energy Solution have unveiled a new milestone in electric vehicle (EV) innovation: the development and planned commercialization of lithium manganese-rich (LMR) prismatic battery cells for use in GM’s future electric trucks and full-size SUVs.

Key Highlights:
• First in Industry: GM is poised to be the first automaker to integrate LMR batteries into EVs.
• Production Timeline: Ultium Cells, a joint venture between GM and LG Energy Solution, aims to begin commercial production of LMR prismatic cells in the U.S. by 2028, with pre-production starting in late 2027.
• Higher Energy Density: The new LMR cells offer 33% more energy density than lithium iron phosphate (LFP) cells, at a similar cost.
• Range and Cost Advantage: GM anticipates electric trucks using these batteries will exceed 400 miles of range while reducing battery pack costs compared to high-nickel battery packs.

Strategic Impact:
• Affordability and Innovation: The LMR chemistry reduces reliance on expensive cobalt by using more manganese, improving affordability without compromising performance.
• U.S.-based Development: Final validation of the battery cells will take place at GM’s new Battery Cell Development Center in Warren, Michigan.
• Technology Leadership: LG Energy Solution holds over 200 patents in LMR tech and has been researching the chemistry since 2010.

Executive Commentary:
• Kurt Kelty, GM VP of Battery, Propulsion, and Sustainability: “We’re pioneering manganese-rich battery technology to unlock premium range and performance at an affordable cost.”

• Wonjoon Suh, LG Energy Solution EVP: “This launch marks the first-ever LMR prismatic cells for EVs and reflects our deep investment in this space.”
The LMR technology will complement GM’s existing Ultium battery platform and aligns with its long-term vision of delivering a wide range of EVs for all customer segments, while enhancing domestic battery production and material sourcing.
