Toyota Partners with Redwood Materials for Sustainable EV Battery Supply
Strategic Collaboration to Boost U.S.-Sourced Battery Components
Toyota is taking a major step toward sustainable electric vehicle (EV) production by partnering with battery recycling startup Redwood Materials. The agreement ensures a domestic supply chain for critical battery materials, reducing reliance on overseas manufacturing.
Key Details of the Partnership
- Materials Supplied: Redwood will provide cathode material and anode copper foil for Toyota’s upcoming $13.9 billion EV battery factory in North Carolina, set to launch in 2025.
- Recycled Content: The cathode materials will contain at least 20% recycled nickel, 20% recycled lithium, and 50% recycled cobalt, while the anode copper foil will be made from 100% recycled copper.
- Financial Impact: While exact terms remain undisclosed, the deal mirrors Redwood’s multi-billion-dollar agreement with Panasonic.
Why This Partnership Matters
Strengthening Domestic Supply Chains
Currently, cathode and anode materials—which account for over 50% of a battery cell’s cost—are primarily manufactured overseas. By sourcing from Redwood’s U.S. facilities, Toyota gains a competitive edge in cost efficiency and supply chain resilience.
Advancing Circular Battery Economy
This collaboration builds on a 2022 recycling agreement where Redwood refurbishes or recycles batteries from Toyota’s hybrid and EV lineup. For non-reusable batteries, Redwood extracts valuable metals like copper, lithium, cobalt, and nickel, repurposing them for new battery production.
With 5 million Toyota electrified vehicles on the road today, this closed-loop system is poised for significant growth.
The Science Behind Lithium-Ion Batteries
Understanding the critical components:
- Cathode (Positive Electrode): Contains lithium, nickel, and cobalt—the most expensive part of the cell.
- Anode (Negative Electrode): Typically uses copper foil.
- Electrolyte: Facilitates ion movement during charging/discharging.
Redwood’s recycling process recovers all these materials, making it a key player in sustainable battery production.
Redwood’s Expansion Plans
Founded by ex-Tesla CTO JB Straubel, Redwood is scaling operations to meet growing demand:
- Nevada Headquarters: Expanding recycling and refining capabilities.
- South Carolina Campus: Slated for construction later this year.
By 2025, Redwood aims to produce enough materials for 1 million EVs annually (100 GWh/year), supporting Toyota’s electrification goals.
The Bigger Picture
This partnership underscores Toyota’s commitment to localized, eco-friendly manufacturing while positioning Redwood as a leader in the U.S. battery recycling revolution.
