Rivian and Redwood Materials have expanded their electric vehicle battery recycling partnership, the companies confirmed this month in a brief announcement carried by industry trade press. The revised agreement widens the categories of Rivian-sourced manufacturing scrap and end-of-life battery packs that Redwood will accept at its Nevada campus, building on a collaboration that had previously been limited to a narrower subset of Rivian's production waste.

Specific terms of the expansion, including new material streams, throughput commitments, and financial figures, were not disclosed in the announcement. Neither company identified a target date for the first commercial deliveries under the revised terms.

Who are the partners?

Redwood Materials, founded in 2017 by former Tesla co-founder and chief technology officer JB Straubel, operates North America's largest dedicated EV battery recycling facility at the Tahoe-Reno Industrial Center in McCarran, Nevada. The company recovers lithium, cobalt, nickel, and copper from battery scrap and electronics waste for reuse in cell production.

Redwood has signaled intentions to scale its cathode-active material output alongside hydrometallurgical recovery lines at the same site. The campus has filed multiple expansion permits with Storey County authorities in recent years.

Rivian, headquartered in Irvine, California, assembles the R1T electric pickup and R1S SUV at a single plant in Normal, Illinois. The company has framed supply chain circularity, including end-of-life battery management, as part of its broader materials strategy.

Current production vehicles use large-format nickel-cobalt-aluminum cylindrical cells supplied by Samsung SDI. Rivian has disclosed plans for a smaller R2 platform and a second assembly plant under construction in Georgia.

What does the expansion cover?

The joint statement does not detail which Rivian product lines or battery chemistries fall under the revised agreement, nor does it specify first-pass recovery yield targets. Redwood has historically accepted manufacturing scrap from cell and pack producers and processed it into cathode-active material precursors at its Nevada site.

End-of-life modules from consumer and fleet vehicles represent the largest forward volume category for any North American processor.

Redwood's disclosed automotive and cell-maker partners include:

• Ford
• Volkswagen
• Panasonic
• Toyota
• Volvo
• Tesla (multi-year agreement dating to Redwood's founding)

Why does it matter?

EV battery recycling capacity in North America remains well below the volumes projected to reach end of first life during the latter half of this decade. Redwood and Li-Cycle operate the two largest commercial-scale battery processing facilities on the continent.

Smaller processors including Ascend Elements and Cirba Solutions are scaling operations at separate sites, while Redwood pursues permits for additional capacity at its McCarran campus.

The U.S. Inflation Reduction Act's Section 45X production tax credit has created a structural demand pull for domestically recovered battery materials. Redwood's hydrometallurgical process produces cathode precursor materials at specifications usable by North American cell manufacturers.

Section 45X provides per-kilogram credits for US-produced battery components, with elevated rates for materials sourced from domestic recycling streams. That regulatory pull links Rivian's recycling commitments directly to its cell sourcing economics.

What happens next?

Neither company published a target date for the first commercial volumes of Rivian-sourced recycled material processed under the expanded agreement. Redwood has filed expansion permits with authorities in Storey County, Nevada, to increase hydrometallurgical and cathode-active material capacity.

Rivian is expected to publish updated sustainability disclosures later this quarter, which may include recycling and circular materials metrics for its manufacturing operations. The company has previously disclosed limited recycling-related figures in annual impact reports, focused on manufacturing waste streams and water use at the Normal facility.

Rivian's next quarterly filing will offer the first formal checkpoint on whether the expanded Redwood agreement translates into disclosed throughput figures. Section 45X credit claims filed for the same period will provide a parallel regulatory signal on whether recovered material from Redwood counts as domestic feedstock for Rivian's battery sourcing.
