Ultium Cells, the joint venture between General Motors and LG Energy Solution, announced that its Tennessee plant will begin producing lithium-manganese-rich (LMR) battery cells, which promise higher energy density than LFP at a similar cost. The cells are scheduled for use in electric trucks and large SUVs starting in 2028.
General Motors plans to upgrade the Ultium Cells facility in Spring Hill to produce battery cells based on lithium manganese-rich (LMR) chemistry, with commercial production in the United States scheduled to begin by 2028. The company says these cells could offer 33% higher energy density than LFP batteries at a similar cost, making them candidates for electric vehicles targeting good range and a lower price.
