by GM and LG are developing new batteries for electric vehicles
General Motors, in collaboration with LG, plans to start producing lithium-manganese-rich (LMR) batteries by 2028. These batteries feature a unique chemical composition with a high manganese content and minimal cobalt. According to the manufacturers, the new batteries will have 33% higher energy density compared to lithium iron phosphate (LFP) batteries at a similar cost.
The companies state that LMR technology is a breakthrough because traditional batteries require large amounts of nickel and expensive cobalt, which significantly increases the price of electric vehicles. This innovation will reduce costs by increasing the proportion of affordable manganese.
“LMR batteries are the result of a decade of development. They contain about 65% manganese, 35% nickel, and are virtually cobalt-free,” noted GM’s Director of Battery Development, Kushal Narayanaswamy.
The new batteries are expected to enable electric pickups to travel over 400 miles (644 km) on a single charge. This could make electric vehicles more affordable – currently, the starting price for some models reaches $75,195.
Although the technology details have not yet been disclosed, engineers are confident that LMR batteries will open up new possibilities for the mass production of electric vehicles. This is particularly relevant for large models such as pickups and full-size SUVs, which require powerful and long-lasting batteries.
