Quick Takeaways
- Honda Princeton NuEnergy lithium-ion battery recycling strengthens circular battery supply chains.
- The collaboration supports advanced recycling technologies and U.S. energy security goals.
On January 13, Honda Motor Co. Ltd. and Princeton NuEnergy Inc. announced the signing of a memorandum of understanding to advance collaboration on next-generation lithium-ion battery recycling technologies. The partnership focuses on joint validation projects and the potential for commercial-scale deployment, reinforcing shared ambitions around sustainability and innovation.
The agreement reflects both companies’ intent to strengthen circular battery materials supply chains while supporting U.S. energy independence through advanced recycling solutions. By aligning technical expertise and long-term strategy, the collaboration aims to reduce reliance on virgin raw materials while improving the resilience of battery manufacturing ecosystems.
Progress in Lithium-Ion Battery Recycling Validation
Since 2022, Honda and Princeton NuEnergy have carried out joint technical validation of plasma-based Direct Recycling and Upcycling technologies. These efforts cover lithium-ion battery manufacturing scrap as well as end-of-life battery materials, addressing critical gaps in conventional recycling processes.
Through this work, Princeton NuEnergy has produced rejuvenated NMC cathode active material with performance characteristics comparable to virgin material. This outcome supports Honda’s long-term objectives for resource circularity and electrification, while demonstrating the commercial relevance of advanced recycling approaches.
Expanding U.S. Manufacturing and Advanced Materials Capabilities
The announcement follows recent recognition of Princeton NuEnergy’s U.S. manufacturing expansion, including the “2025 Smart Move SC New Plant Award.” This milestone highlights progress in scaling advanced battery materials production and contributing to national objectives around critical minerals and energy security.
Together, these capabilities position the collaboration to play a meaningful role in the future of sustainable battery manufacturing and recycling.
