GM And LG Energy Solution Collaborate On Innovative LMR Battery Cell Technology For Electric Vehicles
General Motors (GM) and LG Energy Solution are set to commercialise lithium manganese-rich (LMR) prismatic battery cells for GM's future electric trucks and SUVs. This collaboration builds on their existing partnership to develop prismatic battery cell technology. GM aims to be the first automaker to use LMR batteries in electric vehicles (EVs), with production expected by 2028.
Battery engineers from GM and LG Energy Solution have created a new LMR prismatic battery cell. This innovation offers 33% more energy density than the best-performing lithium iron phosphate (LFP) cells, while maintaining similar costs. The final design of these LMR battery cells will be validated at GM's Battery Cell Development Center in Warren, Michigan, which is anticipated to open earlier in 2027.
The LMR battery cells utilise a higher proportion of manganese, which is more affordable than cobalt, while also delivering greater capacity and energy density. This advancement allows GM's electric truck platform to achieve a leading range using high-nickel chemistry today. By integrating LMR technology with prismatic cells, GM aims for over 400 miles of range in an electric truck, alongside significant cost savings.
"We’re pioneering manganese-rich battery technology to unlock premium range and performance at an affordable cost, especially in electric trucks," said Kurt Kelty, VP of battery, propulsion, and sustainability at GM. "As we look to engineer the ideal battery for each vehicle in our diverse EV portfolio, LMR will complement our high-nickel and iron-phosphate solutions to expand customer choice in the truck and full-size SUV markets."
Ultium Cells, a joint venture between GM and LG Energy Solution, plans to start commercial production of LMR prismatic cells in the United States by 2028. Pre-production is expected at an LG Energy Solution facility by late 2027. This initiative supports strategic investments in domestic battery production and responsible sourcing of critical materials like lithium, graphite, and manganese from North America.
LG Energy Solution holds the largest portfolio of intellectual property related to LMR technology globally, with over 200 patents secured. "We’re excited to introduce the first-ever LMR prismatic cells for EVs," said Wonjoon Suh, executive VP at LG Energy Solution. "GM’s future trucks powered by this new chemistry are a strong example of our shared commitment to offering diverse EV options."
Commitment to Sustainable Growth
GM began exploring manganese-rich lithium-ion battery cells in 2015. The company accelerated development by prototyping LMR cells at its Wallace Battery Cell Innovation Center in Warren. Collaborating with partners, GM engineers advanced cathode materials and cell assembly processes to overcome challenges related to performance and durability.
General Motors is committed to advancing transportation through innovative technology that enhances safety and reduces emissions. Its brands offer a wide range of gasoline-powered vehicles alongside an expanding lineup of EVs as part of its transition towards an all-electric future.
LG Energy Solution is a leading global manufacturer of lithium-ion batteries for various applications including electric vehicles. With extensive research experience and over 69,600 patents worldwide, the company aims for carbon neutrality across its value chain by 2050 while promoting sustainable growth.
This collaboration between GM and LG Energy Solution marks a significant step forward in battery innovation for electric vehicles. By leveraging advanced technologies and strategic partnerships, both companies aim to offer consumers diverse options while contributing positively towards sustainable development goals.
