GM Confirms Spring Hill Plant for Mass Production of LMR EV Batteries

General Motors has confirmed that its next-generation lithium-manganese-rich (LMR) batteries will be mass-produced at the Ultium Cells joint venture plant in Spring Hill, Tennessee. Factory upgrades start later this year and finish by 2028, when the first EVs with the new cells are expected to launch.

• The Spring Hill, Tennessee plant will be the world's first to mass-produce prismatic LMR cells
• LMR batteries promise 33% more range than LFP and over 400 miles of EPA range
• LMR cells should cost nearly the same as LFP thanks to lower cobalt and nickel content
• The first GM EVs with LMR batteries are expected in 2028
