Solid-state batteries are considered one of the most promising solutions for the next generation of electric vehicles and energy storage systems. By replacing liquid electrolytes with solid materials, they offer greater safety, higher energy density, and the potential for faster charging.
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).
The new company brings together Syensqo’s leadership in advanced materials with Axens Group’s proven expertise in process design, industrial scale-up and global operation of in-organic chemistry industrial plants, complemented by IFPEN’s renowned know-how in inorganic chemistry and expertise in oxide or sulfide divided materials at its Lyon research center.
"The creation of Argylium represents an important step forward in bringing solid-state battery materials to market readiness. By joining forces with Axens and IFPEN, we are enhancing the chances of successfully scaling up Syensqo’s pilot innovations and contributing to advance Europes electrification and energy storage ambitions.", said Thomas Canova, Head of R&I at Syensqo.
Fabrice Bertoncini, Axens Group’s Executive Vice President in New Development and Transformation adds: "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."
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.
