Closing the Loop on EV Batteries

General Motors (GM) has announced a significant milestone in its sustainability efforts, confirming that it has successfully utilized 100% recycled nickel, cobalt, and manganese in the production of new electric vehicle battery cells. This achievement is the result of a strategic collaboration with Cirba Solutions, which focused on recovering critical materials from end-of-life GM battery packs.


The pilot program has already moved from the testing phase to real-world application. This month, vehicles equipped with these recycled battery materials rolled off the production lines at GM's Factory Zero in Detroit and the Spring Hill Assembly plant in Tennessee. The models currently incorporating these batteries include specific variants of the Cadillac Lyriq, Vistiq, and Escalade IQ, as well as the Chevrolet Silverado EV Trail Boss and the GMC Sierra EV AT4.


The Engineering Behind the Pilot

According to Melissa Flaherty, Director of Sustainable EV Battery Ecosystem at GM, the initiative required years of intensive coordination across the battery supply chain, involving partners such as Ultium Cells and LG Energy Solution. The process began with the recovery of 80 end-of-life battery packs. At a specialized facility in Ohio, Cirba Solutions processed these units into a "black mass" blend, which was then refined into 12 metric tons of cathode active material.


«This pilot shows that the value of an EV battery can extend well beyond its first life — and that strong partnerships across the battery ecosystem are essential to building a more circular, resilient future for battery technology,» noted Flaherty.

Setting New Standards for Performance

Integrating recycled content into high-performance EVs required meeting the same rigorous safety, quality, and performance benchmarks as virgin materials. GM had to re-validate both the recovered substances and the final battery cells to ensure they met the automaker's exacting specifications.


While industry methods for material recovery are rapidly evolving, current technological capabilities allow for impressive recovery rates:

  • Lithium: Up to 80% recovery.
  • Nickel, Cobalt, and Manganese: Approximately 95% recovery.

Beyond this specific pilot, GM is already repurposing over 70% of battery pack components through its refurbishment programs. Furthermore, the company continues to explore broader supply chain resiliency, including a previously announced partnership with Redwood Materials to recycle production scrap and cathode material from its Ultium Cells plants.


Looking Toward a Sustainable Future

Although GM has not yet disclosed the specific cost savings associated with scaling this recovery process, the initiative aligns with the company’s broader strategy to manage its long-term battery supply chain. In addition to recycling, GM is utilizing roughly 10,000 batteries for second-life applications in what it describes as the largest second-life battery microgrid in North America.


As the company continues to refine these processes, the focus remains on environmental impact. As Flaherty concluded, the initiative serves as a clear pathway for reducing the carbon footprint associated with battery production while potentially lowering costs for future consumers.
