Rivian’s Factory Will Soon Be Powered Partly By Old Batteries From Its Own EVs

The electric automaker is one of the first customers of Redwood Materials’s new energy storage business, which takes old or discarded EV batteries—in this case, from Rivian’s own vehicles—and deploys them in a second life on the grid.
