Lithium Ark secured a European patent granting the refining process for converting lithium chloride into battery-grade lithium hydroxide through a circular, lower-footprint route.

Lithium Ark is a lithium technology and project development company advancing next-generation, low-carbon refining solutions for the battery value chain. With offices in Chile and the Netherlands, we combine decades of hands-on lithium processing and environmental engineering experience with three international patents covering circular refining routes that convert LiCl into battery-grade LiOH or Li₂CO₃. Our Green+ process is designed to reduce CO₂ emissions, energy and water consumption while improving cost competitiveness and scalability, and it is ready for industrial deployment. Our flagship project, Green+ Antwerp, is a lithium refinery under development in the Antwerp chemical cluster (Belgium), designed to strengthen Europe’s “made-in-Europe” battery materials supply chain through secure sourcing, industrial-grade execution, and long-term partnerships with EU customers.
