Syensqo and Axens have launched Argylium, a joint venture focused on scaling the production of advanced materials for solid-state batteries within Europe. This partnership aims to bolster the continent's battery supply chain by accelerating the commercial demonstration of high-performance components for next-generation energy storage.

This new venture merges Syensqo's advanced material leadership with Axens' process design and plant operations, enhanced by IFPEN's deep inorganic chemistry expertise, especially in oxides/sulfides, to accelerate next-gen battery material development, creating a comprehensive force for innovation in solid-state batteries.

“The creation of Argylium represents an important step forward in bringing solid-state battery materials to market readiness,” said Thomas Canova, Head of R&I at Syensqo. “By joining forces with Axens and IFPEN, we are enhancing the chances of successfully scaling up Syensqo’s pilot innovations and contributing to advance Europe’s electrification and energy storage ambitions.”

“With over 50 years experience in scaling up technologies to the commercial levels, in partnership with IFPEN and aligned with our strategy to develop industrial assets in Europe for the production of advanced battery materials for cathodes (CAM) and recycling of Black Mass, our association with Syensqo aims to lay the groundwork and build a robust ecosystem for the commercialization of solid electrolytes by 2030,“ said Fabrice Bertoncini, Axens Group’s Executive Vice President in New Development and Transformation.

Argylium will strengthen collaboration with leading European research institutions, automotive OEMs, advanced battery manufacturers and energy technology partners to drive innovation and market readiness, contributing to Europe’s ambition of building a sustainable and competitive solid-state battery industry.

Building on Syensqo’s successful operation of a solid-state battery pilot line in La Rochelle, and over a decade of technology development at its State-of-the-art Paris laboratory (Aubervilliers), Argyilum will focus on accelerating the industrialization of next-generation Sulfide Solid Electrolyte materials to the next-generation All-Solid-State Batteries (ASSB).
