General Motors (GM) and LG Energy Solution have introduced a fresh take on EV batteries with their new lithium manganese-rich (LMR) cell. Designed for GM’s upcoming electric trucks and SUVs, the battery offers a 33% boost in energy density compared to today’s top lithium iron phosphate (LFP) options – a development that could soon see vehicles comfortably reaching over 400 miles on a single charge.
The partnership, realised through their joint venture Ultium Cells, is gearing up for full-scale production in the U.S. by 2028, with pre-production set for late 2027. This collaboration not only aims to power next-generation EVs but also boosts domestic manufacturing and materials sourcing.
In a welcome change from older battery designs that lean heavily on costly cobalt and nickel, these LMR cells use more manganese. This shift helps to cut material costs while delivering improved energy density, opening up the possibility for even longer journeys in GM’s utility vehicles.
Kurt Kelty, GM’s Vice President of battery, propulsion, and sustainability, explained, “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, expand customer choice and help drive American battery innovation.” Wonjoon Suh from LG Energy Solution echoed that sentiment, emphasising the shared commitment to offering a broad range of EV options that cater to real-world needs.
This LMR prismatic cell, the result of a decade of refined engineering at the Wallace Battery Cell Innovation Centre in Warren, Michigan, will be validated at GM’s new Battery Cell Development Centre opening in 2027 and at LG’s own facilities. If you’ve ever wrestled with range anxiety, this innovation is a solid step towards easing those concerns.
