Pure Lithium Corporation, a Boston-based lithium metal battery technology company, announced a joint development agreement with Saint-Gobain Ceramics, a global leader in specialty ceramic materials. The joint development agreement will accelerate the production of Pure Lithium’s patent-pending lithium selective, water-blocking membranes for lithium metal anode production from brine.

Additionally, Pure Lithium invented a flexible lithium conducting membrane for next-generation lithium metal battery applications, which will serve as both a solid electrolyte and separator in a lithium metal battery. Saint-Gobain Ceramics will also scale this technology.

Saint-Gobain Ceramics teams are ready to co-develop with Pure Lithium innovative membranes to revolutionize the lithium extraction and battery markets. They can rely on our strong expertise in this segment and unique R&D capabilities. These solutions are key to supporting the electrical transition worldwide.

—Nicolas Miègeville, CEO Saint-Gobain Ceramics

Saint-Gobain designs, manufactures and distributes materials and services for the construction and industrial markets. Pure Lithium is a Boston-based lithium metal battery technology company led by inventor and lithium expert, CEO Emilie Bodoin, and world-renowned battery and metallurgical expert, MIT Emeritus Professor Donald R. Sadoway, as full-time CSO.

The company’s novel Brine to Battery technology combines metal extraction and anode production, unlocking unconventional sources of lithium. The resulting pure lithium metal anode is the core component of the company’s lithium metal vanadium oxide battery, a step-change improvement over today’s lithium-ion technology in cell performance, cost, and safety. Additionally, the battery is free of graphite, cobalt, nickel, and manganese.
