Pure Lithium Partners with Saint-Gobain to Accelerate Lithium-Metal Battery Membranes

Saint-Gobain

Strategic Collaboration Aims to Advance Next-Generation Battery Technology

US-based battery innovator Pure Lithium has partnered with Saint-Gobain Ceramics to accelerate the production of lithium-metal battery membranes. This collaboration leverages Saint-Gobain’s advanced manufacturing capabilities to commercialize cutting-edge battery separator membranes, a crucial component in next-generation lithium-metal batteries.

Boosting Lithium-Metal Anode Development

Pure Lithium will use Saint-Gobain’s production capacity and R&D expertise to scale up its membrane technology. These membranes enable the electrodeposition of lithium onto substrates to form high-performance lithium-metal anodes or function as separators within battery cells. This advancement aims to enhance energy density and battery efficiency, meeting the increasing demand for high-performance energy storage solutions.

Collaboration with E3 Lithium on Lithium-Vanadium Batteries

As part of its expansion strategy, Pure Lithium is developing a lithium-metal anode in partnership with Canadian lithium developer E3 Lithium. This initiative aligns with the company’s vision to introduce lithium metal-vanadium batteries, incorporating vanadium-based cathode materials to improve battery longevity and stability.

Paving the Way for Next-Generation Energy Storage

The partnership with Saint-Gobain Ceramics and collaboration with E3 Lithium position Pure Lithium as a key player in the future of lithium-metal battery technology. These efforts support the transition towards higher-performance energy storage for EVs, grid storage, and portable electronics.

Pure Lithium Secures $300mn EXIM Support for US-Based Lithium Metal Battery Facility

Pure Lithium Corporation

Pure Lithium has received a $300 million Letter of Interest (LOI) from the Export-Import Bank of the United States (EXIM) to support its planned industrial-scale lithium metal battery plant. If approved, the Pure Lithium EXIM loan would fall under EXIM’s “Make More in America” initiative aimed at rebuilding domestic manufacturing capacity and securing supply chains in strategic sectors like energy storage.

The proposed facility will use Pure Lithium’s proprietary “Brine to Battery” process, which directly converts brine into lithium metal anodes—eliminating graphite, cobalt, nickel, and manganese. This vertically integrated method enables a fully US-based battery supply chain, from raw material extraction to cell production. CEO Emilie Bodoin emphasized the project's potential to reshape global lithium battery sourcing models.

Disruptive Battery Chemistry Supports Strategic US Objectives

The Pure Lithium EXIM loan could accelerate commercialization of lithium metal vanadium oxide batteries, which offer higher energy density without relying on traditional cathode materials. This technology positions Pure Lithium at the forefront of post-Li-ion battery innovation, directly supporting the U.S. push for clean tech self-reliance.

Pure Lithium’s partnerships reinforce its vertically integrated vision. It sources lithium concentrate from E3 Lithium in Alberta, Canada, and collaborates with Saint-Gobain Ceramics to engineer water-blocking lithium-selective membranes—a key component in its novel extraction process.

EXIM Financing to Boost US Battery Supply Chain Resilience

EXIM’s Make More in America strategy supports projects that improve domestic industrial competitiveness in sectors facing global strategic risk. The Pure Lithium EXIM loan would directly address U.S. concerns over dependence on foreign-dominated battery material supply chains, especially China.

If finalized, the funding will catalyze Pure Lithium’s ability to scale manufacturing within U.S. borders while lowering barriers for next-generation battery adoption. This aligns with U.S. energy security goals and rising demand for alternative battery chemistries in defense, mobility, and grid storage sectors.

The Metalnomist Commentary

The Pure Lithium EXIM loan represents a critical step in reshoring advanced battery manufacturing. As supply chain risks intensify and lithium metal demand grows, projects that fuse innovation with domestic sourcing will shape the next era of U.S. battery independence.

Maryland EV battery manufacturer secures $20 million US grant

Ion Storage Systems

Ion Storage Systems, a Maryland-based manufacturer, has been awarded a $20 million federal grant this week to accelerate the commercialization of its solid-state lithium battery for the electric vehicle market.

The grant, provided by the US Department of Energy, will aid Ion in developing nonflammable batteries utilizing ceramic electrolyte manufacturing. According to the Department of Energy, this method has the potential to reduce greenhouse gas emissions from battery production by 50%.

Ion is collaborating on this four-year, $40 million project with Saint-Gobain, a supplier of ceramics and glass, and KLA, a manufacturer of chip-making tools.

Furthermore, Ion announced it is working with government agencies to expand the applications of its solid-state battery technology in the defense and aerospace sectors.
