Mercedes-Benz Opens Lithium-Ion Battery Recycling Plant in Germany

Battery Recycling Plant

Mercedes-Benz has inaugurated its advanced lithium-ion battery recycling facility in Kuppenheim, southern Germany, marking a significant step in its mission to establish a closed-loop system for critical minerals essential for electric vehicle (EV) production.

The new plant aims to process 2,500 metric tonnes per year of active and inactive materials from shredded battery modules. The active material, known as black mass, contains high-value critical minerals such as nickel, lithium, and cobalt. These will be refined and reused to produce over 50,000 battery modules annually for Mercedes-Benz's EV lineup.

Innovative Recycling Process

The facility utilizes a cutting-edge mechanical-hydrometallurgical process, which Mercedes-Benz claims can recover more than 96% of battery-grade critical minerals from spent lithium-ion batteries. The mechanical phase sorts and separates inactive materials like plastics, copper, aluminum, and iron. Meanwhile, the hydrometallurgical phase processes the black mass to extract critical minerals for reuse in battery production.

Sustainable Operations

Mercedes-Benz's Kuppenheim facility is powered entirely by green electricity, incorporating a photovoltaic system with a peak output of over 350 kilowatts. This aligns with the company's broader commitment to sustainability and reducing carbon emissions.

Technology Partnership with Primobius

The plant was developed in collaboration with Primobius, a joint venture between Australian process technology innovator Neometals and German engineering firm SMS. Mercedes-Benz's subsidiary Licular spearheaded the project, leveraging Primobius' expertise to implement cutting-edge recycling technologies.

Future Expansion Potential

While the Kuppenheim plant represents a significant milestone, Mercedes-Benz is cautious about scaling operations further. A spokesperson highlighted that production volumes could expand in the "medium to long term," contingent on insights gained from the facility’s initial operations.

This recycling initiative underscores Mercedes-Benz's dedication to creating a sustainable supply chain for critical minerals, enhancing EV production, and reducing environmental impact.
