GM Unveils Game-Changing Battery, Aims for Affordable 400-Mile EVs
General Motors (GM) and LG Energy Solution have announced plans to commercialize lithium manganese-rich (LMR) prismatic battery cells for future GM electric trucks and full-size SUVs, providing a 33% higher energy density compared to the best lithium iron phosphate (LFP)-based cells, all at a comparable cost. Kurt Kelty, VP of battery, propulsion, and sustainability at GM, emphasized that the new battery cells will be especially prevalent within the automaker's electric truck lineup, with over 400 miles of available range while optimizing savings over their high-nickel pack, which currently supplies segment-leading range in those electric trucks. The pre-production of LMR prismatic cells will begin at an LG Energy Solution facility by late 2027. GM will be the first automaker to deploy the tech in EVs with full commercial production in 2028. Ultimately, GM's upcoming use of LMR battery tech reduces production and buyer costs while maintaining impressive range and promoting domestic battery production through responsible sourcing of materials like lithium, graphite, and manganese in North America. GM has been researching manganese-rich lithium-ion battery cells since 2015, prototyping the technology at its Wallace Battery Cell Innovation Center in Warren, Michigan. Overcoming LMR legacy challenges in performance and durability involved GM and its partners "engineering advanced cathode materials, electrolytes, additives, form factors, and cell assembly processes." The challenges have consisted of significant cobalt usage posing expense challenges, struggles to match the energy density of nickel-manganese-cobalt batteries, and structural stability issues during charge cycles. Over nearly a decade, GM engineers' work involved prototyping 18 cell variations representing 1.4 million miles of driving, TechSpot reports. LG Energy Solution has over 200 patents in this tech field, with its first LMR patent secured in 2010. LG Energy Solution is a spin-off company of LG Chem, a leading global maker of lithium-ion batteries for EVs, energy storage systems, mobility, and IT. The organization aims to achieve carbon neutrality across its business process chain by 2050. Wonjoon Suh, executive VP and head of the Advanced Automotive Battery division at LG Energy Solution, added in GM's announcement: "We're excited to introduce the first-ever LMR prismatic cells for EVs, the culmination of our decades-long research and investment in the technology." LMR battery tech's ability to integrate into GM's battery supply chain and cell manufacturing promotes investments in domestic battery production and the responsible sourcing of critical materials from North America. This achievement is especially significant with President Trump's recently imposed tariffs, which push to localize supply chains and reduce reliance on imported battery materials. The LMR battery's prismatic design replaces the pouch format used in GM's current high-nickel packs, allowing for more efficient packaging in larger trucks and SUVs. This optimized packaging lowers the number of necessary parts and reduces costs, theoretically creating savings for consumers. Cost reduction here is vital, as GM electric trucks with leading range, like the 2025 Chevrolet Silverado EV LT Extended Range, hold a $75,195 base price. GM's current electric truck lineup uses NMCA batteries with 5% cobalt, but the automaker's upcoming LMR tech uses "virtually no cobalt," according to its press release.

This Groundbreaking Battery Tech Is Coming In 2026, But What Is It?
If you think Detroit automakers are laggards in offering electric vehicles (EVs), guess again. General Motors is currently leading the pack, offering the Cadillac Celestiq, Cadillac Escalade IQ, Cadillac Lyriq, Cadillac Lyriq-V, Cadillac Optiq, Cadillac Vistiq, Chevrolet Blazer EV, Chevrolet Equinox EV, Chevrolet Silverado EV, GMC Hummer EV Pickup, GMC Hummer EV SUV, and GMC Sierra EV, all of which are fueled by electrons, not petroleum. General Motors and LG Energy Solution are developing lithium manganese-rich prismatic battery cells, or LMRs, for use in future GM vehicles. GM plans to be the first automaker to use LMR batteries in its EVs beginning in 2028. The breakthrough battery chemistry will allow for electric vehicle (EV) batteries that are 30% more energy dense than current ones, yet cost the same as the lithium iron phosphate batteries, or LFPs, currently in use. "We're excited to introduce the first-ever LMR prismatic cells for EVs, the culmination of our decades-long research and investment in the technology," said Wonjoon Suh, executive vice-president and head of the Advanced Automotive Battery division at LG Energy Solution. "GM's future trucks powered by this new chemistry are a strong example of our shared commitment." The announcement follows a similar one made by Charles Poon, Director of Electrified Propulsion Engineering at Ford, on April 23rd. "This isn't just a lab experiment. We're actively working to scale LMR cell chemistry and integrate them into our future vehicle lineup within this decade." Poon cited the LMR batteries' lower production cost, higher energy density, enhanced stability and safety as key factors in their superiority. Ford started their EV offerings with nickel-cobalt-manganese (NCM) batteries, later adding lithium-iron-phosphate (LFP) batteries in 2023. To understand how these batteries differ from those currently in use, you must understand how a battery works. Simply put, electricity is produced in a battery from a reaction between the anode, which creates electrons, and a reaction in the cathode, which absorbs them. Electrolytes allow the electric charge to flow between the cathode and the anode. The net product is electricity. GM's Ultium platform currently employs nickel manganese cobalt aluminum oxide batteries, also known as NCM, which uses 85% nickel, 5% cobalt, and 10% manganese for its cathode coating. However, cobalt and nickel are expensive, and cobalt is known to be mined with child labor, which is a human rights concern. Another widely used battery chemistry is lithium iron phosphate, or LFP, which costs about 20% less than an NCM battery, but China has a near monopoly in LFP cell manufacturing, according to S&P Global. In contrast, LMR batteries use roughly 35% nickel, 65% manganese, and virtually no cobalt. Given that it's the fifth most common element on Earth and widely available, manganese is far less expensive than nickel and cobalt. LMR batteries cost roughly the same to produce as LFP batteries, while being 33% more energy dense. GM plans to produce rectangular prismatic cells rather than the pouch cells currently being used, enhancing the packaging efficiency and reducing the number of components by as much as 75%. Additionally, LMR chemistry works well with bigger cell sizes, which lowers system costs even more. While the Chevrolet Silverado EV Work Truck with Max Range has an EPA-rated range of 492 miles, it uses an NCM battery. Using an LMR battery would allow GM to deliver similar range and lower the price, which now starts at $57,095 and tops out at $97,895. While GM began researching manganese-rich lithium-ion battery cells in 2015, performance and durability haven't been up to par. Historically, they've suffered from a short lifespan, losing voltage in a short period of time, but GM and LG Energy Solution state that they have overcome such obstacles by "adding proprietary dopants and coatings, along with particle engineering, process innovations, to achieve the right energy density and arrangement of battery materials inside the cell to keep them stable," according to a GM press release. The research and development at GM's Wallace Battery Cell Innovation Center in Warren, Michigan, has led to the corporate partners holding more than 200 patents around the world on LMR-related technology. Ultimately, GM sees the technology providing more range at a lower cost, which should help bring down the cost of EVs, a sticking point in their journey towards being more widely accepted. According to Cox Automotive, the average price paid for a new car in March 2025 was $47,462. By comparison, the average price paid for an electric car was $59,205 – a 22% price premium and the highest in a couple of years. Such price realities are driving the research to reduce battery costs, while tariffs are pushing automakers to rely less on China for their minerals and components.
