General Motors plans to use a new type of battery in its electric vehicles which it says will be more affordable to produce.
The automaker is working with the battery manufacturer LG Energy Solution to commercialize lithium manganese-rich prismatic battery cells to use in future electric trucks and full-size SUVs, the companies said Tuesday.
The new battery cells use a higher proportion of manganese, which is more affordable than other battery materials. They are also expected to provide greater capacity and energy density, with the companies' newest LMR prismatic battery cell offering 33% higher energy density compared with the best-performing lithium iron phosphate battery, GM and LG said.
A joint venture between the two companies, known as Ultium Cells, plans to start commercial production of the cells in the U.S. by 2028. Pre-production is set to begin at an LG facility by late 2027. GM plans to conduct final production-design at a new development center in Warren, Mich., which is expected to open in early 2027.
