General Motors (GM) is set to revolutionize electric vehicle (EV) technology with the introduction of lithium manganese-rich (LMR) prismatic battery cells, aiming for implementation in its full-size electric SUVs and trucks, including the Chevrolet Silverado and Escalade IQ, by 2028. This new battery technology leverages more abundant and cost-effective minerals like manganese, reducing reliance on cobalt and nickel.
GM’s LMR cells promise enhanced vehicle performance, longer range, and affordability, positioning the automaker to gain a competitive edge in the EV market. Kurt Kelty, GM’s vice president of battery production, posits that the LMR battery will significantly advance electric truck capabilities. The company is developing these batteries in collaboration with LG Energy Solution, anticipating commercial production in the U.S. by 2028 following preproduction starting in late 2027.
Historically, LMR batteries have suffered from shorter lifespans, but GM claims to have resolved this issue. The new prismatic design will also contribute to weight reduction in EVs, with plans for battery packs to include 50% fewer components and modules, enhancing efficiency.
LMR batteries will complement GM’s existing battery technologies and are expected to provide a 33% increase in energy density, translating to additional miles on the road. Though specific pricing details remain undisclosed, experts estimate costs may drop to $80-$90 per kilowatt-hour, compared to current levels.
As GM invests heavily in electrification, the LMR initiative is part of a broader strategy to enhance EV adoption by addressing key consumer concerns like cost and range, with plans to achieve over 400 miles of range in their electric trucks.
