GM joint venture Ultium plant in Ohio begins battery cell production

Ultium Cells LLC has started production of battery cells at its first manufacturing operation in Warren, Ohio, the General Motors Co. and LG Energy Solution joint venture company confirmed Wednesday. 

For competitive reasons, what date production launched was not specified but Ultium Cells spokesperson Brooke Waid confirmed it started in August. The plant will supply battery cells for GM’s Ultium platform-based EVs, including the GMC Hummer EV pickup and SUV built at Factory Zero Detroit-Hamtramck Assembly Center. 

Mike Kelecava and Ryan Miely inspect a battery cell as it proceeds through the cell assembly line at the Ultium Cells LLC plant in Warren, Ohio.

GM and LG invested $2.3 billion in the Warren, Ohio, facility that has more than 40 gigawatt hours of annual capacity with room for expansion.

Ohio Gov. Mike DeWine went to the plant Wednesday to see the cell manufacturing process performed by a team of more than 800 workers. At full production, the facility will have 1,300 employees.

GM and other automakers are vertically integrating battery cell production to help lower the cost of their batteries and electric vehicles. The start of Ultium battery cell production brings GM closer to its electrification goals since it needs additional supply to make and sell more EVs. 

Battery cells proceed through the end-of-the-line formation process at the Ultium Cells LLC plant in Warren, Ohio.
