Redwood Materials Secures $425M Series E as Google Joins Strategic Investor Roster

Redwood Materials, the rapidly rising battery recycling and materials manufacturing company founded by Tesla co-founder JB Straubel, has officially closed its $425 million Series E funding round. The round introduces Google as a significant new strategic investor alongside NVIDIA’s NVentures, underscoring a powerful connection between the energy transition and the exponential rise of artificial intelligence.

This funding event marks a major milestone—not just for Redwood Materials, but for the broader battery, EV, clean energy, and AI ecosystems. As pressure intensifies on the global electricity grid from electrification and AI megaprojects, the alignment between energy storage companies and tech giants signals a new era of strategic collaboration.

Below is an in-depth look at why this round matters, how Redwood Materials is positioned in the global battery supply chain, and what Google and NVIDIA’s involvement reveals about the future of AI infrastructure and sustainable energy.

Redwood Materials at a Glance: Building America’s Circular Battery Supply Chain

Founded in 2017 by JB Straubel—Tesla’s longtime CTO—Redwood Materials set out to tackle one of the most overlooked challenges in the energy transition:

➡ Where will all the critical battery materials come from?
➡ How can the U.S. reduce dependence on foreign suppliers?
➡ How do we solve the end-of-life problem for EV and consumer electronics batteries?

While traditional mining remains essential, Straubel realized that a truly sustainable electrification strategy required a closed-loop ecosystem, where lithium, nickel, cobalt, and copper could be continually recycled from end-of-life batteries and manufacturing scrap.

Today, Redwood Materials:

• Operates one of the largest battery recycling facilities in North America
• Processes gigawatt-hour scale scrap from EV makers and battery manufacturers
• Extracts critical materials and remanufactures them into battery-grade products
• Supplies U.S. EV manufacturers with sustainable, domestic materials
• Is building new facilities to produce cathode active material (CAM) and anode copper foil, the most expensive parts of a lithium-ion battery

In short, Redwood is becoming a full-stack domestic battery materials supplier, combining recycling, refining, and manufacturing under one roof.

This vertically integrated model is rare—and extremely valuable—as demand for batteries surges across EVs, grid storage, and AI-driven data centers.

A $425 Million Series E: Why This Funding Round Is Pivotal

Redwood’s $425M Series E is among the most significant late-stage clean-tech raises in recent years, reaffirming investor confidence in both:

1. The circular battery economy, and
2. The U.S. domestic materials supply chain

Notably, the round is not only about capital—it’s about strategic alignment. Google’s entry and NVIDIA’s continued participation through NVentures signal a deepening connection between energy storage and AI infrastructure.

Where the new capital will go

Redwood Materials stated that it plans to use the new funds to:

• Scale its domestic battery materials production, particularly CAM and copper foil
• Expand recycling operations to handle larger volumes of EV batteries
• Invest in U.S.-based refining capacity for lithium, nickel, and cobalt
• Accelerate new long-term supply contracts with automakers and cell manufacturers
• Build new facilities supporting 100 GWh+ annual output

The U.S. market is entering a phase where automakers need massive quantities of battery materials—far more than existing domestic supplies can provide. Redwood’s expansion directly supports the national effort to localize the battery supply chain.

Why Google Joined Redwood Materials’ Series E

Google’s participation is one of the most important signals of the round.

At first glance, the connection between a search engine giant and a battery materials company may not seem obvious. But in reality, few companies face greater pressure from the global energy crisis than Google.

AI Data Centers Are Becoming One of the Largest Energy Consumers in the World

The rise of generative AI has fundamentally changed Google’s power needs.

• Training a single large AI model can consume millions of kilowatt-hours
• Data centers powering AI inference must run 24/7 at extremely high loads
• GPU clusters require uninterrupted, stable electricity, often from renewable sources

Google recently reported that AI workloads are pushing its electricity usage dramatically higher. As AI expands across search, cloud computing, and enterprise tools, the company is experiencing:

• Soaring energy demand
• Increasing grid instability risks
• Growing dependence on battery-backed renewable energy

Why Google Needs Redwood Materials

By investing in Redwood Materials, Google advances several strategic goals:

1. Secure access to cost-effective, long-duration battery storage
2. Support the expansion of domestic battery manufacturing
3. Reduce the carbon footprint of its data centers
4. Partner with a company capable of supplying materials for large-scale energy storage systems

Google has committed to operating all its data centers on 24/7 carbon-free energy—a far more difficult target than simply offsetting with renewables. Achieving that means installing massive amounts of battery storage near its energy-intensive AI facilities.

Redwood’s recycled, U.S.-made materials could power precisely those systems.

NVIDIA’s NVentures: Reinforcing the AI–Energy Feedback Loop

NVIDIA’s participation is equally telling. As the global leader in GPUs, NVIDIA sits at the very center of the AI explosion.

Every wave of demand for NVIDIA chips triggers a corresponding surge in:

• Data center construction
• Power usage
• Renewable energy procurement
• Battery storage needs

As GPU clusters scale into the tens of thousands of units, the energy footprint becomes enormous.

AI scaling = energy scaling

The math is simple:

• More GPUs → exponentially more power
• More power → exponentially more grid stress
• Grid stress → exponential need for energy storage
• Energy storage → exponential need for batteries
• Batteries → exponential need for lithium, nickel, and cobalt

By backing Redwood Materials, NVIDIA is supporting the upstream resources required to keep AI infrastructure growing.

The Clean Energy Trifecta: EVs, Grid Storage, and AI

Redwood Materials sits at a critical intersection of three fast-expanding industries:

1. Electric Vehicles (EVs)

Automakers including Toyota, Ford, and Tesla are scaling U.S. battery production dramatically. Each EV requires 50–100 kWh of battery capacity, and the materials inside those batteries account for almost half the total cost.

2. Grid-Scale Energy Storage

Renewable energy is growing, but solar and wind are intermittent. Utility companies are deploying enormous battery banks—many of them using chemistries that rely on materials Redwood can supply or recycle.

3. AI and Data Centers

Hyperscalers like Google, Amazon, Microsoft, and NVIDIA consume staggering amounts of electricity. As AI demand grows, these companies need reliable storage more than ever.

Redwood effectively provides the raw materials needed for all three of these megatrends.

The U.S. Battery Supply Chain Challenge—and Redwood’s Solution

For decades, the U.S. has relied heavily on foreign countries—especially China—for battery materials and manufacturing.

This creates vulnerabilities:

• Geopolitical risk
• Transportation delays
• Cost volatility
• Environmental concerns
• National security implications

Redwood Materials aims to change that by creating a localized, circular supply chain that is:

• More sustainable
• More resilient
• More affordable
• More secure

How Redwood’s closed-loop system works

1. Collect batteries from EVs, consumer electronics, and manufacturing scrap
2. Recycle to extract lithium, nickel, cobalt, copper
3. Refine materials back to battery-grade purity
4. Remanufacture into CAM and copper foil
5. Supply to domestic cell factories
6. Repeat once batteries reach end-of-life

This loop reduces the environmental footprint and lowers long-term material costs.

Why This Series E Signals a New Era for Clean Tech Funding

Clean-tech investment has historically been cyclical, with periods of high enthusiasm followed by downturns. But Redwood Materials is proving that:

• Battery recycling is not a niche—it is infrastructural.
• Domestic materials production is a national priority.
• AI companies are now major players in the energy sector.

Google and NVIDIA joining this round marks a new phase where tech giants no longer just consume energy—they invest upstream to secure it.

What’s Next for Redwood Materials?

Following this raise, Redwood is positioned to:

• Expand its Nevada and South Carolina campuses
• Increase recycled material output dramatically
• Grow partnerships with automakers and battery manufacturers
• Support utility-scale storage deployment
• Further integrate AI-driven automation into material processing
• Potentially explore international expansion

Redwood’s ultimate goal is ambitious but clear:

Become one of the world’s largest producers of sustainable battery materials.

And with strategic support from tech giants who depend on stable energy, the company is better positioned than ever to scale.

Why Redwood’s Series E Matters for the Future of Energy and AI

Redwood Materials’ $425 million Series E is more than a funding milestone—it’s a strategic realignment of some of the world’s most influential industries.

• AI needs clean, reliable power.
• Clean power needs large-scale energy storage.
• Energy storage needs sustainable battery materials.
• And Redwood Materials is building exactly that supply chain.

With Google joining as a new strategic investor and NVIDIA reinforcing its support, this round represents a growing recognition that the future of AI and the future of energy are now inseparable.

Redwood Materials is no longer just a battery recycling company—it is becoming a cornerstone of America’s clean energy and AI infrastructure.
