Ultium Cells LLC, a joint venture of General Motors and LG Energy Solution, will invest more than $2.3 billion to build its second battery-cell manufacturing plant in the United States. The approximately 2.8 million-square-foot facility will be located in Spring Hill, Tenn. It is expected to create 1,300 new jobs. Construction will begin immediately, and the plant is scheduled to open in late 2023. Once operational, the facility will supply battery cells to GM’s Spring Hill assembly plant.
Ultium batteries are unique because the large-format, pouch-style cells can be stacked vertically or horizontally inside the battery pack. This allows engineers to optimize battery energy storage and layout for each vehicle design. Energy options range from 50 to 200 kilowatt hours, which could enable a GM-estimated range up to 450 miles or more on a full charge with 0-60 mph acceleration in 3 seconds. GM’s future Ultium-powered EVs are designed for Level 2 and DC fast charging. Most will have 400-volt battery packs and up to 200-kW fast-charging capability, while GM's truck platform will have 800-volt battery packs and 350-kW fast-charging capability.
South Korea-based LG Energy established its first research facility in the United States in the early 2000s. The company built its first U.S battery plant in Holland, Mich., in 2010. Through Ultium Cells, LG Energy Solution and GM will merge their advanced technologies and capabilities to help accelerate automotive electrification.
