In March, Lauren McDonald was on hand for GM’s EV Day, during which much of the discussion was about the new Ultium batteries GM and LG Chem will be manufacturing at a new battery factory just down the road from the former Lordstown, Ohio assembly plant. That factory is projected to have an annual capacity of 30 gigawatt-hours of battery cells. While GM made a bunch of grandiose claims about its campaign to bring electric cars to market that day, few actual details about the Ultium battery emerged during the presentation.
