US' lithium battery recycling plant offers yield exceeding 97%

Princeton NuEnergy (PNE) has launched the United States’ first commercial-scale battery recycling facility in Chester, South Carolina, achieving a recycling yield exceeding 97%. This advanced plant produces battery-grade cathode active materials and critical battery minerals domestically, supporting a secure and circular U.S. battery supply chain. The facility is fully permitted, surpasses industry recovery norms, and plans to expand capacity from 15,000 tons per annum (tpa) in 2026 to potentially 50,000 tpa as demand grows. PNE’s technology, developed from Princeton University research, utilizes a patented low-temperature plasma-assisted separation process (LPAS) that recovers nearly all lithium-ion materials across battery chemistries, offering a 38% cost reduction and 69% lower environmental footprint compared to conventional methods. PNE is also advancing direct recycling technologies through a joint pilot facility in Texas and operates the largest Materials Testing Center in the U.S. northeast, facilitating third-party validation and accelerating
