GM will spend $1B making the first manganese-rich cells in mass production

General Motors and LG Energy Solution will invest $1 billion to convert the Spring Hill, Tennessee plant into the first factory to mass-produce prismatic lithium-manganese-rich cells. Production will begin later this year and run through 2028. The cells use less cobalt and nickel and deliver 33% higher energy density than lithium-iron-phosphate cells at comparable cost. They target full-size pickups and SUVs with over 400-mile range. The project follows a $2.575 billion commitment and builds on a pilot line in Warren, Michigan that produces 2,500 cells per day.
