Retired EV batteries could be repurposed as grid storage, extending their useful life beyond vehicle use.
Battery-grade cathode active material manufactured from recycled lithium-ion batteries and supplementary mined feedstock at Redwood's Nevada campus. The CAM is compatible with NMC and LFP chemistries and is designed to supply North American battery cell manufacturers including Panasonic. The first CAM production building has capacity for ~20 GWh annually, with multiple buildings planned to scale toward supply for millions of EVs.
Ultra-thin battery-grade copper foil produced from recycled copper recovered during the battery recycling process, manufactured domestically in Nevada. Replacing imported Asian foil for US battery factories, Redwood's foil closes the supply chain loop by re-entering recycled copper directly as a battery-ready component. Production commenced in 2023 and supplies customers including Panasonic's Kansas gigafactory.
End-of-life battery collection, processing, and hydrometallurgical refining service accepting lithium-ion batteries from EVs, consumer electronics, and manufacturing scrap. Redwood recovers lithium, nickel, cobalt, and copper at recovery rates exceeding 95%, then refines them to battery-grade purity for reuse in new cells. Partners include Panasonic, Toyota, Ford, and Rivian, with plants in Nevada and South Carolina.
