Honda Motor Co., Ltd. and Princeton NuEnergy Inc. have signed a memorandum of understanding (MOU) to explore collaboration on next-generation recycling technologies for lithium-ion batteries. The agreement, announced on January 5, 2026, reflects both companies’ shared goal of strengthening the circular supply chain for battery materials and enhancing U.S. energy independence through advanced recycling and rejuvenation methods.
Since 2022, Honda and Princeton NuEnergy have worked together to validate the performance of plasma-based direct recycling and upcycling processes for manufacturing scrap and end-of-life battery materials. In these joint technical studies, Princeton NuEnergy’s technology produced rejuvenated nickel-manganese-cobalt (NMC) cathode active material with performance characteristics comparable to those of newly manufactured material. This achievement supports Honda’s long-term objectives for resource circularity and vehicle electrification.
Under the terms of the MOU, the two organizations will establish a framework for collaborative validation projects and assess the feasibility of scaling these recycling methods to commercial production. The agreement aligns with Honda’s global electrification strategy and Princeton NuEnergy’s mission to expand the cost-effective, closed-loop production of battery-grade cathode active materials in the United States.
Dr. Chao Yan, Co-Founder and CEO of Princeton NuEnergy, said: “Our work with Honda shows strong technical alignment and a clear pathway for advancing circular battery materials. This MOU reflects a shared commitment to accelerating the next phase of sustainable, high-performance material production, and we look forward to continuing our collaboration.”
Honda Motor Co., Ltd.: “Honda values the progress achieved through our collaboration with PNE and recognizes the importance of advanced recycling technologies in building a more sustainable materials ecosystem. This MOU represents an important step forward in our efforts to advance long-term solutions that support our global electrification strategy.”
The announcement follows Princeton NuEnergy’s recent recognition for its U.S. manufacturing expansion, including the 2025 Smart Move SC New Plant Award. With continued growth and expanded collaboration with Honda, Princeton NuEnergy is well positioned to help build a modern, circular, domestic supply chain for lithium-ion battery materials, supporting broader industry resilience and national energy-security priorities.
