General Motors and LG Energy Solution have announced a major advancement in electric vehicle battery technology with the development of lithium manganese-rich (LMR) prismatic cells. These new batteries promise 33% higher energy density than lithium iron phosphate (LFP) cells, offering over 400 miles of range in electric trucks while significantly reducing costs. GM plans to commercialize the technology by late 2027, with full-scale production beginning in 2028 through its Ultium Cells joint venture. The LMR chemistry relies on a higher proportion of manganese, a more affordable and abundant material than nickel or cobalt, making EVs more cost-effective. The companies aim to integrate these cells into GM’s future electric trucks and SUVs, marking a significant step toward long-range, affordable EVs.
