Revolutionizing Electric Vehicle Battery Recycling: JB Straubel’s Redwood Materials
JB Straubel, co-founder and former CTO of Tesla, is on a mission to build the world’s largest electric vehicle (EV) battery recycling company through his startup, Redwood Materials. Founded in 2017, Redwood aims to create a circular supply chain for lithium-ion batteries, sourcing them from automakers, dealers, parts suppliers, dismantlers, and waste management firms. As Edward Sanchez, a senior analyst at automotive consultancy TechInsights, notes, “If someone can do it, it’s JB Straubel.”

Scaling Up Recycling Capacity
Redwood is racing to quintuple its recycling capacity from 100 GWh today to 500 GWh annually by 2030, enough for about five million EVs. To achieve this goal, the company is building a $3.5 billion battery materials and recycling facility in Ridgeville, S.C., which will produce cathode and anode components for future vehicles and employ 1,500 people in the U.S. “Battery Belt.” Straubel has raised concerns about the soaring energy demands of A.I. and its potential strain on future power supplies.
Addressing A.I.’s Energy Demands
In June, Straubel launched Redwood Energy to tackle the issue by repurposing second-life battery packs to power data centers and stabilize the electric grid. Redwood Energy has struck a deal with Crusoe, a company focused on sustainable energy for A.I., to power a new data center in Abilene, Texas. The project will run on a 63-MWh microgrid designed to operate independently from the main electricity network.
The Role of A.I. in Battery Recycling
Experts believe that machine learning could help companies like Redwood build a closed-loop battery supply chain, reducing U.S. dependence on China-controlled components such as cobalt, lithium, and nickel. A growing number of institutions are exploring how A.I. could drive economies of scale in three areas critical to recycling: battery diagnostics, disassembly, and refining. Dr. Gavin Harper, a researcher at the University of Birmingham, is investigating how computer vision and robotic arms might help recyclers save time and money.
Streamlining the Recycling Process
Machine learning can streamline the “gateway testing and triage” process used to assess a battery’s health and sort it by chemistry type and manufacturer specifications. For example, EV batteries from Tesla, GM, and BMW all use different chemistries, cell formats, and connectors. Once an A.I. system identifies the battery type, it can generate an automated disassembly plan and direct robotic arms to execute the work far faster and more safely than humans.
Ali Khazaeli, an independent battery data scientist, notes that A.I. models can automatically detect the cathode’s materials and optimize the reductive calcination process. This can help recover valuable charge metals, including cobalt, nickel, manganese, and lithium, and use them to build new cathodes for fresh cells.
Challenges and Opportunities
Redwood faces steep logistical challenges, rising capital costs, and a potential shortage of used batteries as it tries to scale. The company reported $200 million in revenue in 2024, but it remains unclear whether it’s profitable. However, analysts believe that A.I.-driven automation could help Straubel’s company scale, especially as it looks to incorporate consumer-electronics batteries into its operations.
Edward Sanchez agrees that A.I.-driven automation could help Redwood scale, particularly as it explores the “gold mine” of cellphones, iPods, and laptops that no longer have a use for consumers but whose batteries are still valuable. While Redwood has not announced partnerships with consumer electronics giants such as Apple or Samsung, Sanchez believes such deals “will make sense in the future.”
