General Motors is making strides in the electric vehicle industry with its upcoming battery technology that promises even more savings than previously anticipated. The automaker is set to introduce locally-produced lithium manganese-rich (LMR) prismatic battery cells in 2028, which will be featured in full-sized SUVs and trucks. These new LMR batteries are estimated to provide a range of over 400 miles, a significant improvement over current battery options.
GM’s focus on developing low-cost electric vehicle batteries in the U.S. is part of its strategy to compete with China in this rapidly growing market. The company’s latest battery chemistry advancements may surpass the industry standard lithium-iron-phosphate (LFP) battery in terms of cost-efficiency and performance. GM CEO Mary Barra emphasized the potential savings of LMR batteries due to their reduced nickel and cobalt content, making them a more cost-effective option compared to LFP batteries.
LMR batteries utilize a higher proportion of manganese, which is more abundant and cost-effective to mine than nickel and cobalt. This new chemistry allows for a more secure and domestic supply chain, reducing reliance on foreign sources like China. Ford is also exploring LMR batteries as automakers seek to develop cheaper and more sustainable battery solutions for electric vehicles.
GM plans to start production of LMR cells in partnership with LG Energy Solution in 2027, with the batteries expected to be integrated into trucks and SUVs by 2028. These batteries are projected to offer a range of over 400 miles, similar to GM’s current battery technology. The cost savings associated with LMR batteries are anticipated to be substantial, providing a more affordable option for consumers.
In addition to LMR batteries, GM is also launching a Chevy Silverado EV trim with LFP batteries in 2027, offering a range of about 350 miles at a lower cost. The next-generation Chevy Bolt EV will also feature LFP batteries, further expanding GM’s portfolio of electric vehicles with cost-effective battery options.
The company recently announced plans to convert a portion of its Tennessee factory for local production of LFP batteries, highlighting its commitment to developing a resilient and secure American-oriented supply chain. GM’s innovative approach to battery technology is paving the way for more affordable and sustainable electric vehicles in the future.
