Belgian materials company Syensqo and French clean fuels firm Axens Group have launched Argylium, a new company that will focus on developing and scaling up the industrialization of sulfide solid electrolyte materials for all-solid-state batteries (ASSBs).

The new company builds on Syensqo’s solid-state battery pilot line in La Rochelle and more than a decade of technology development at its Paris laboratory.

Argylium brings together Syensqo’s work on advanced materials and Axens Group’s experience in process design, industrial scale-up and global operation of in-organic chemistry industrial plants. That will be complemented by French public research organization IFPEN’s expertise in inorganic chemistry as well as oxide or sulfide divided materials at its Lyon research center.

Argylium will focus on collaborating with European research institutions, automotive OEMs, battery manufacturers and energy technology partners to drive innovation and  bring ASSBs to commercial production, contributing to Europe’s goal of building a sustainable and competitive solid-state battery industry.

“With over 50 years of experience in scaling up technologies to 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 VP, New Development and Transformation.
