GM unveils fourth-generation EV platform using cheaper LMR batteries

General Motors has detailed its fourth-generation electric vehicle platform, which will use exclusively cheaper lithium manganese-rich batteries.

General Motors has detailed its fourth-generation electric vehicle platform, confirmed to launch exclusively with lithium manganese-rich (LMR) battery cells. GM president Mark Reuss announced the development at the GM Forward event in New York, stating the platform would underpin vehicles in the automaker's highest-volume segments, delivering 'lower costs, long range, and improved performance' to mainstream EV buyers.

LMR cells use more manganese and less of the expensive nickel and cobalt found in today's high-nickel batteries. Ultium Cells, GM's joint venture with LG Energy Solution, says LMR can offer up to 33 per cent more energy density than lithium iron phosphate at comparable cost.

GM chief product officer Sterling Anderson said the team originally expected to need a second, long-range battery chemistry alongside LMR but made 'tremendous gains' in getting LMR to work as the exclusive battery of the platform. The company simulated more than 300,000 LMR battery configurations before building a single prototype. Last month, GM confirmed the Ultium Cells plant in Spring Hill, Tennessee, will be the first in the world to mass-produce prismatic LMR cells, with first LMR-equipped vehicles due in 2028.
