General Motors (GM) plans to launch its first electric vehicles powered by lithium manganese rich (LMR) battery technology in 2028. Kurt Kelty, GM’s VP of battery, propulsion, and sustainability, told the Financial Times that the company has resolved the critical technical issue of voltage fade.
This technology aims to revive U.S. electric vehicle demand following a recent market slowdown. Industry observers characterize the shift to LMR as an ambitious and risky strategy.
LMR batteries offer production costs comparable to less expensive lithium iron phosphate (LFP) chemistry. The new cells provide significantly higher energy density than LFP, which enables longer driving ranges for future GM models.
