Altris and Draslovka Partner to Scale Europe’s First Sodium-ion Battery Technology Supply Chain
Altris, a Swedish sodium-ion battery developer, and Draslovka, a global leader in speciality chemicals, have entered a strategic partnership to build Europe’s first industrial-scale sodium-ion cathode value chain. Under the comprehensive agreement that includes a total 19.3 MEUR in-kind investment by Draslovka in Altris, the two companies will scale fully connected production of Altris’ patented sodium-ion cathode active material (CAM) at Draslovka’s facility in Kolín, Czech Republic, supplying up to 350 tonnes of CAM annually.
Draslovka and Altris are partnering to convert an existing line at Draslovka’s Kolín facility for production of Altris’ sodium-ion CAM, enabling rapid time-to-market and capital-efficient scale-up. Once ramped, the line will support production of up to 350 tonnes annually – a European-controlled supply equivalent to around 175 MWh of sodium-ion cell capacity.
As part of the agreement, Draslovka is making a new in‑kind 19.3 MEUR strategic investment in Altris to co-fund the conversion of the production line in Kolín. This also secures long-term access to Draslovka’s licences, process know‑how and a jointly developed plant design for Altris. Progressing at pace, start of production is planned for late Q3 or early Q4 2026.
The partnership comes as Europe accelerates efforts to localise battery materials and move beyond lithium‑only supply chains. By producing CAM in Kolín and preparing for larger-scale capacity at the site, Altris and Draslovka are creating a Western, sodium‑ion-based alternative that reduces reliance on imported inputs, enabling a more resilient and balanced battery ecosystem.
“This exciting partnership with Altris is an important milestone for Draslovka, as we continue strategically investing in concrete opportunities to leverage our world class expertise in chemistry and sustainable technology. By establishing a fully connected value chain production capacity in Europe, we are in a position to deliver high-quality sodium-ion solutions without relying on external links in the chain,” says Pavel Brůžek, CEO of Draslovka.
“This alliance exemplifies how Altris is building a European sodium-ion value chain with leading industrial partners. Europe is no longer waiting for sodium-ion to mature else where – we are industrialisingit here, with Western manufacturing and Western supply. It reflects our strategy to focus on what we do best: delivering world-class cathode material that supports a more resilient European battery supply,” says Christer Bergquist, CEO of Altris.
