On May 14, LG Energy Solution announced plans to commercialize the jointly developed lithium-manganese-rich (LMR) prismatic battery cells with GM starting in 2028.

The company stated that Ultium Cells, the joint venture between LG Energy Solution and GM, plans to begin commercial production of LMR prismatic battery cells at manufacturing facilities in the United States by 2028, with pilot production scheduled to take place at LG Energy Solution’s facilities by the end of 2027.

The LMR battery is a next-generation battery technology that increases the proportion of manganese in the cathode material. By using a greater amount of affordable manganese instead of expensive cobalt and nickel, it enhances cost efficiency while still providing higher capacity and energy density.

Although LMR batteries have been researched for a long time, their short lifespan has limited their commercial viability.

LG Energy Solution and GM explained that they have addressed these issues and that, compared to lithium iron phosphate (LFP) battery cells, LMR battery cells can achieve 33% higher energy density at the same cost.

LMR batteries are planned to be used in the Chevrolet Silverado electric truck and the large electric sport utility vehicle (SUV) Escalade IQ, with a target driving range of over 664 kilometers.

Suh Wonjun, Executive Vice President and Head of Automotive Battery Business Division at LG Energy Solution, described the LMR battery cell as "the result of decades of research and technological investment," adding, "GM’s future trucks powered by this new technology are a strong example of our joint commitment to providing consumers with a diverse range of electric vehicle options."
