Swedish sodium-ion battery developer Altris and specialty chemicals leader Draslovka have partnered to establish Europe’s first industrial-scale sodium-ion cathode value chain.

Draslovka is investing €19.3 million ($22.8 million) in-kind to convert its Kolín, Czech facility for production of Altris’ patented cathode active material (CAM), targeting up to 350 tonnes annually equivalent to ~175 MWh of cell capacity.

The partnership secures long-term access to Draslovka’s licenses, know-how, and joint plant design, enabling rapid, capital-efficient scale-up.

Production is expected by late Q3 or early Q4 2026.
