Gm and Lg Energy Solution Develop New Lmr Battery Cell

General Motors (GM) and LG Energy Solution have developed a new lithium-manganese-rich (LMR) battery cell. This battery aims to reduce electric vehicle costs without compromising range. The LMR cell is slated for initial deployment in pickups and large SUVs starting in 2028. It marks the first commercial application of prismatic EV battery cells by Ultium Cells LLC. GM's current EVs use pouch cells with nickel, manganese, cobalt, and aluminum cathodes. The new LMR cells are more cost-effective due to manganese being cheaper than nickel and cobalt. Prismatic cells are also more efficient and easier to assemble. According to GM, LMR cells offer a 33% higher energy density compared to LFP cells. Prismatic battery packs require half as many components as pouch cells. Production is planned in a new joint venture plant with Samsung SDI starting in 2027. GM plans to offer various battery options for models, allowing customers to choose between price and range. High-nickel batteries will remain suitable for premium applications or customers desiring the highest range.
