Mercedes-Benz Partners with Rock Tech for Sustainable Battery Production



Rock Tech, a cleantech company that aims to produce lithium hydroxide for electric vehicle batteries, is building a refining plant in Guben, Germany. The project is seen as a significant step for Germany's goal to become a hub of modern industry, sustainable mobility, and high technology. The plant will strengthen Brandenburg's position as a center of electromobility and energy transition in Germany, and help to create a closed-loop lithium production system. Rock Tech is developing a proprietary refining process aimed at increasing efficiency and sustainability. The Guben converter is the first of five converters that Rock Tech intends to build in Europe and North America. The converter shall start commissioning in mid-2025 and will produce qualified battery-grade lithium hydroxide in 2026.
