NORTH ANDOVER, Mass. and RENO, Nev., -- Aqua Metals, Inc. (NASDAQ: AQMS) (“Aqua Metals"), a pioneer in sustainable lithium-ion battery recycling, and 6K Energy, a leader in the production of sustainable materials for lithium-ion batteries, today announced a partnership to develop the next generation of low-carbon battery materials and plans to establish a long-term agreement for 6K Energy’s PlusCAM™ cathode material manufacturing plant. Both Aqua Metals and 6K Energy (“the Companies”) share the vision of creating a domestic low-carbon supply chain for critical battery materials and advancing cost-effective production methods for sustainable lithium-ion batteries.

The Companies have initiated the partnership with a non-recurring engineering (NRE) agreement to further develop low-carbon technology for the conversion of critical metals, first virgin and later recycled material, into battery-grade cathode active material (CAM) precursors, which are essential to 6K Energy’s advanced cathode manufacturing. Aqua Metals is leading the development of the innovative conversion process, designed to replace chemical catalysts with clean electricity, and enables the sustainable production of cost-effective CAM precursors by eliminating embedded emissions, recurring expenses, and chemical waste byproducts.

"Manufacturing a genuinely sustainable, lithium-ion battery within the U.S. demands new industrial competencies and leapfrog technologies like our UniMelt microwave plasma," said Thanh Nguyen, Senior VP of Deployment for 6K Energy. “Integrating 6K Energy’s low cost, ultra-sustainable cathode manufacturing capabilities at our PlusCAM factory with Aqua Metals’ low-carbon innovative conversion process sets a new standard in minimizing emissions in lithium battery manufacturing.”

Addressing a primary challenge of next-generation battery manufacturing, 6K Energy and Aqua Metals are fostering a future where sustainable, high-performance lithium batteries are made in the U.S. from domestically sourced materials. Cathode active material is the most expensive component in a lithium battery, and it is currently manufactured almost exclusively in China. This partnership not only creates low-carbon resources for battery and electric vehicle manufacturers but also enables greater supply independence at a competitive cost and less production time than imported materials from foreign sources.

"Aqua Metals believes that the key to sustainable energy lies in leveraging the full potential of recycled materials in manufacturing lithium-ion batteries, building a circular supply chain domestically, and minimizing the environmental impact of the clean energy industry,” said Steve Cotton, President & CEO of Aqua Metals. “Our commitment to pioneering low-carbon, closed-loop battery recycling powered by electricity aligns perfectly with 6K Energy's groundbreaking sustainable cathode manufacturing, and our partnership signifies a major step towards U.S. leadership in the next generation of net-zero battery materials and technologies.”

6K Energy was recently awarded a $50 million Department of Energy (DOE) grant opportunity that will partially fund the $200+ million PlusCAM factory in Jackson, TN, scheduled to open in 2025. The conversion process already in development is based on Aqua Metals’ patented and commercially-proven AquaRefining™ technology, and is designed to work with both virgin materials and sustainably recycled content supplied by Aqua Metals. As part of the strategic agreement, 6K Energy will fund the project for low carbon pCAM conversion in 2023, and the successful completion of the development project will lead to a long-term supply agreement between the two companies.

The Companies plan to co-locate pCAM manufacturing with 6K Energy’s PlusCAM factory. PlusCAM will be the world’s first UniMelt® plasma cathode manufacturing plant, providing low cost, ultra-sustainable production of battery material in the U.S., with production capacity of 13,000 tons per annum (tpa). Aqua Metals currently operates the world’s first sustainable lithium battery recycling facility at its Li AquaRefining™ pilot and is developing a five-acre, 10,000tpa clean metals recycling campus nearby in the Tahoe-Reno Industrial Center. Aqua Metals’ patented AquaRefining recycling technology recovers critical metals from spent lithium batteries using electricity in a closed loop, lowering emissions, and reducing landfill waste by 95% compared to current battery recycling processes.
