Redwood Materials, co-founded by Tesla's J.B. Straubel, used a Tesla Cybertruck to transport 10,000 pounds of recycled battery materials in Nevada. This showcases the Cybertruck's utility in heavy-duty work and supports Redwood's mission to create a circular supply chain for battery materials. Redwood is expanding its operations, including building a cathode plant, and has raised significant capital for enhancing its capacity and selling U.S.-produced battery materials. The company's efforts are crucial as the demand for lithium-ion batteries is expected to increase substantially.
