General Motors is now making the battery cells for its GMC Hummer EV and SUV, both to be built at Factory Zero in Detroit.
Ultium Cells LLC, the joint venture between GM and LG Energy Solution, said Wednesday it had started production at its new battery cell factory in northeast Ohio.
Ohio Gov. Mike DeWine toured the $2.3 billion Ultium plant in Warren on Wednesday to see the battery cell manufacturing process first hand, Ultium spokeswoman Brooke Waid said.
When asked when the plant started operations, Waid declined to disclose specific information citing competitive reasons. She wrote in an email to the Free Press, "We have chosen to recognize these milestones internally as One Ultium Team. We are happy to share the process of the Ultium Cells team with Ohio Gov. DeWine today."
