Lithium Battery Recycling Achieves Over 97% Efficiency

Princeton NuEnergy is establishing a domestic supply chain for critical battery materials with its new facility in the U.S., which recycles old lithium batteries with an efficiency of over 97%.
A new facility opened in South Carolina, U.S., has taken a significant step toward strengthening the critical material supply chain by recycling old lithium batteries with high efficiency. Established by Princeton NuEnergy (PNE), this facility is the country’s first commercial-scale center for producing “black mass” and battery-grade cathode materials. Black mass refers to a special recyclable material extracted from batteries, which is concentrated with valuable metals.
Over 97% Recycling Efficiency

The facility recovers critical minerals locally from batteries, achieving a recycling rate of over 97%, which is well above industry standards. Fully permitted and compliant with all legal requirements, the facility produces high-quality battery raw materials. The company announced that the plant’s capacity will increase to 15,000 tons per year by 2026, with the potential to scale up to 50,000 tons depending on market demand.
The company’s developed low-temperature plasma-assisted separation (LPAS) process provides cathode and anode materials that can be used directly in battery manufacturing. This method reduces costs by 38% and lowers environmental impact by 69% compared to traditional techniques.
PNE aims to create a circular battery economy in the U.S. by combining its other investments with this new facility. Recycling raw materials can be sourced from various items, including mobile phones, computers, children’s toys, electric vehicles, and industrial energy storage systems.
