Quick Takeaways
- The launch of Argylium signals a major step toward industrializing sulfide solid electrolytes for all-solid-state batteries in Europe.
- By combining deep materials science with proven scale-up expertise, the venture aims to shorten the path from lab research to automotive-grade ASSB production.
Syensqo Argylium solid-state batteries took a significant step forward with the launch of Argylium, a newly formed company focused on advancing and commercializing next-generation materials for solid-state batteries in Europe. The initiative is designed to accelerate the transition from laboratory innovation to industrial-scale production for advanced battery technologies.
Argylium builds on Syensqo’s established solid-state battery pilot line in La Rochelle and more than ten years of sustained research and development at its advanced Paris laboratory in Aubervilliers. This strong foundation positions the new venture to shorten development timelines while maintaining technical rigor and material performance standards.
Syensqo Argylium Solid-State Batteries and Sulfide Electrolytes
At the core of Syensqo Argylium solid-state batteries is the industrialization of sulfide solid electrolyte materials, a critical component for all-solid-state batteries. These materials are essential for enabling higher energy density, improved safety, and faster charging compared to conventional lithium-ion battery technologies.
Argylium’s technical focus includes:
Industrial Scale-Up Expertise Supporting ASSB Development
The new company combines complementary strengths across the value chain. Axens contributes deep expertise in process engineering, industrial design, and the global operation of inorganic chemistry plants, enabling reliable and cost-effective scale-up of complex materials.
This capability is further reinforced by IFPEN’s long-standing know-how in inorganic chemistry, particularly in oxide and sulfide divided materials developed at its Lyon research center. Together, these competencies create a robust pathway from pilot-scale validation to full industrial deployment.
By uniting advanced materials innovation with proven industrial execution, Argylium aims to accelerate Europe’s role in next-generation battery manufacturing and support the broader adoption of all-solid-state battery technologies across automotive and energy storage applications.
