Rock Tech Lithium Inc. (TSXV: RCK) has received funding from Germany’s Federal Ministry for Research, Technology and Space (Bundesministerium für Forschung, Technologie und Raumfahrt) to advance its “ELiSePro – Efficient Lithium Recovery Using Selective Processes” project. The initiative aims to enhance lithium yield at the company’s Guben converter facility, strengthening Germany’s raw material independence and supporting the European battery supply chain.
Developed in partnership with RWTH Aachen University, the €250,000 project will test advanced ion separation technologies — including nanofiltration, capacitive deionization, and lithium-ion sieves — to reduce lithium losses in processing. Results will be assessed using both economic and technological metrics, with direct application to industrial operations at Guben. Findings are expected to be published in scientific journals and considered for patent protection.
“This funding supports the technological advancement of the German and European battery industry,” said Rock Tech CEO Mirco Wojnarowicz. “Even though it’s a relatively small amount, it’s an important step toward building additional know-how, securing critical raw materials, and creating sustainable value chains in Europe.”
The award marks the third public funding program Rock Tech has secured in recent months, adding to €800,000 from EIT RawMaterials under the KAVA program and C$388,000 from Ontario’s Critical Minerals Innovation Fund for lithium ore sorting technologies. Rock Tech’s German converter project has been designated a strategic initiative under the EU Critical Raw Materials Act (CRMA).
