About
Founded in 2019, Princeton NuEnergy is a U.S.-based advanced materials manufacturer developing proprietary, closed-loop processes for lithium-ion battery materials production. Our platform is built around patented low-temperature plasma-assisted separation technology, enabling the recovery, purification, and rejuvenation of battery materials without breaking cathode active material down into basic metal salts.
Today, PNE is focused on two near-term commercial priorities: producing Rejuvenated Cathode Active Materials through Cathode-to-Cathode® direct recycling and manufacturing high-purity Advanced Black Mass™ for flexible downstream processing.
With facilities in South Carolina, New Jersey, and Texas, PNE is scaling a domestic platform designed to strengthen critical minerals security, reduce production costs, and support a more resilient U.S. battery supply chain.
