Oct 2025Series EEclipse Ventures (lead); NVentures; Goldman Sachs; Capricorn Investment Group; Alphabet$425M$6BRedwood Materials, founded in 2017 by former Tesla CTO JB Straubel and headquartered in Carson City, Nevada, specializes in battery recycling, cathode production, and materials for the electric vehicle supply chain sustainability, while expanding into energy storage solutions. The company recovers over 70% of used or discarded battery packs in North America, stockpiling more than 1 gigawatt-hour of batteries for repurposing as of June 2025, with plans to deploy 20 gigawatt-hours of grid-scale storage by 2028. Its new Redwood Energy business ties retired EV batteries to renewable sources like wind and solar to power AI data centers and industrial sites off-grid or connected to the grid, natural gas, or future nuclear. On October 23-24, 2025, Redwood Materials raised $350 million in an initial Series E funding round, led by Eclipse Ventures with participation from Nvidia's NVentures and others like T. Rowe Price, achieving a post-money valuation of $6 billion—up from $5 billion previously according to some reports. The company later announced a final close bringing the total Series E to $425 million. Funds are allocated to accelerate energy storage deployments, expand refining and materials production capacity, and grow engineering and operations teams amid the AI data center power boom. Redwood, with over 1,500 employees, entered unicorn status in 2021 and positions itself in the CleanTech sector to meet surging demand for scalable, reliable power from repurposed EV batteries. This round underscores investor confidence in its execution, supply chain innovations, and pivot to high-growth energy storage for AI infrastructure, differentiating it from pure recycling peers by creating value from battery second-life applications.

The round was co-led by Goldman Sachs Asset Management and Capricorn's Technology Impact Fund, with participation from T. Rowe Price Associates, Microsoft Climate Innovation Fund, Deepwater Asset Management, Caterpillar, and others including OMERS and Future Positive (per investor lists). It achieved a post-money valuation over $5 billion, bringing total equity raised to over $2 billion plus a $2 billion DOE loan commitment. The funds support expansion of Redwood's U.S. battery supply chain, including a 175-acre recycling facility in Sparks, Nevada for anode copper foil production starting end-2023, and a 600-acre campus near Charleston, South Carolina for cathode and anode materials remanufacturing. Panasonic is an early customer for copper foil from Tesla Gigafactory scrap recycling since 2019. The round aligns with U.S. efforts to onshore battery production amid electrification growth.

The post-money valuation reached $3.7 billion according to sources familiar with the deal, enabling expansion of operations from Carson City, Nevada, including tripling facility size and building a new site, creating over 500 jobs. This funding built on prior rounds, including a $40M Series B in 2020, positioning Redwood to scale production of battery materials domestically amid growing demand for EV supply chains.
Sep 2020Undisclosed stageClimate Pledge Fund (lead); Breakthrough Energy Ventures; Amazon; Capricorn Investment Group$40M-Redwood Materials is a battery recycling company founded by Tesla co-founder JB Straubel that develops and commercializes technologies for recycling end-of-life lithium-ion batteries and e-waste into high-value metals and chemicals including cobalt, nickel, lithium, and copper. The company's mission is to build a closed-loop supply chain for electric vehicle batteries that reduces environmental impact and feeds recycled materials back into battery production. In September 2020, Redwood Materials received its first major investment from Amazon's newly launched Climate Pledge Fund as one of five inaugural companies. The company also raised $40 million in the same period from Capricorn Investment Group and Breakthrough Energy Ventures, an environmental fund backed by Jeff Bezos and Bill Gates. The company had recently emerged from stealth mode and was testing its recycling process with scrap materials from Panasonic's operations at Gigafactory Nevada while establishing recycling partnerships.
Apr 2017Seed-$2M-Redwood Materials received its first outside funding in 2017, the year JB Straubel founded the company after serving as chief technology officer of Tesla. The early money funded the start of work on recycling lithium-ion batteries and the scrap generated by battery manufacturing, a business that grew out of Straubel's experience building the Gigafactory supply chain. Redwood began with a small team in Carson City, Nevada, processing battery production scrap and end-of-life cells to recover cobalt, nickel, copper and lithium for reuse in new cells. Over the following years it signed supply and recycling arrangements with Panasonic and other cell makers and raised increasingly large rounds, including $40 million in 2020, more than $700 million in July 2021 and more than $1 billion in 2023. The company describes its aim as a closed-loop domestic supply chain for electric vehicle battery materials.
