About Redwood Materials
Redwood Materials builds a circular supply chain for lithium-ion batteries by recycling end-of-life cells and manufacturing cathode active materials and copper foil for EV and grid-storage makers. The privately held company, founded in 2017 by JB Straubel and headquartered in Carson City, Nevada, also deploys large-scale energy storage systems. Its model combines collection and processing of batteries with U.S.-based production of critical materials such as lithium, nickel, cobalt, and copper.
