How LMR Batteries Could Transform the Future of the EV Market

GM’s new LMR batteries promise over 400 miles of EV range with lower costs, higher energy density, and minimal cobalt, aiming for U.S. production by 2028 with Ultium Cells.

General Motors is set to transform EV battery tech with its upcoming lithium manganese rich (LMR) batteries, developed in partnership with LG Energy Solution.

After a decade of research and solving key issues like short lifespan and voltage loss, GM will commercialize LMR prismatic cells in the U.S. by 2028, targeting electric trucks and full-size SUVs.

Unlike current high-nickel batteries, LMR uses 65% manganese, 35% nickel, and nearly no cobalt, drastically reducing costs while delivering strong performance. These new cells will offer 33% more energy density than LFP at comparable cost, with the goal of enabling over 400 miles of range in EV trucks.

LMR will use a prismatic form factor, improving manufacturing efficiency and reducing battery pack components by up to 50%, ideal for large EVs.

Advanced engineering and proprietary materials now give LMR cells lifespans and stability on par with today’s top batteries.

Tested over 1.4 million simulated EV miles, and backed by 200+ patents, GM’s LMR batteries promise high range at lower cost. Production will be led by Ultium Cells, reinforcing GM’s strategy to deliver affordable, long-range EVs and expand leadership in electric trucks like the Chevrolet Silverado EV.
