Operations have been restored at Ultium Cells LLC's battery plant in Warren, Ohio, after a chemical leak temporarily halted activity in the cathode mixing area, the company confirmed Wednesday.
An Ultium spokesperson did not provide details on when cathode mixing operations resumed or whether an internal investigation of the leak is still underway.
The company said it took "immediate steps" to contain a cathode mixing slurry leak that occurred over the weekend at its Ohio production plant. Area mixing operations had been paused while Ultium assessed the situation and worked with a third-party company on the cleanup. Operations at other parts of the plant were not affected.
No employees were exposed or injured in the spill, the company said.
