Altris and Ligna Develops the World’s First Ultrathin Sodium-Ion Battery

Altris is taking another step in building a smarter and more resilient European battery ecosystem. Together with Ligna, Jemac and RISE, the company is developing the world’s first ultrathin sodium-ion battery for next-generation connected electronics – an effort supported by Vinnova and fully developed in Sweden.

Altris and Ligna

Together with Swedish partners Ligna and Jemac, Altris is developing the world’s first ultrathin sodium-ion battery – designed for the next generation of connected electronics and produced entirely in Sweden. With this partnership, Altris and its partners strengthens the wider ecosystem, helping Europe advance toward a truly sustainable and competitive battery industry.

“Developing the world’s first ultrathin sodium-ion battery shows what focused collaboration across the value chain can achieve. By combining our cathode technology with Ligna’s manufacturing expertise and the capabilities of Jemac and RISE, we are accelerating innovation in Europe while reducing reliance on imported materials. Europe will not win by building bigger, but by building smarter – together”, says Christer Bergquist, CEO of Altris.

With support from Vinnova, the project moves from concept to commercial reality by combining:

  • Altris’ industrialised sodium-ion cathode technology
  • Ligna’s roll-to-roll thin-cell manufacturing
  • Jemac Sweden AB’s hardware integration expertise
  • RISE Research Institutes of Sweden’s testing and validation capabilities

This collaboration demonstrates how focused specialisation across the value chain accelerates innovation and reduces Europe’s dependency on imported battery materials. By pioneering ultrathin sodium-ion cells, Altris aim to unlock safer, more sustainable alternatives for small electronics, wearables and IoT.

About Altris

Altris is a Swedish sodium-ion battery developer, with primary focus on its proprietary Prussian White cathode material. Sprung out of the Ångström Laboratory at Uppsala University, we are taking our patented innovation from conception to commercialization. Looking ahead, we aspire to become the primary supplier of sodium-ion battery cathodes in Europe, making a real impact on the world by enabling a better battery at scale.

Why Sodium‑Ion Batteries Are Becoming a Strategic Asset for European Defence

Stockholm, Sweden

The war in Ukraine has shown how vulnerable modern societies are when energy systems come under attack. Repeated power cuts have made reserve solutions essential for keeping hospitals, communications and other essential services running in below‑freezing temperatures – and proven that batteries and energy storageare now a core component of total defence. Against this backdrop, and with European states heavily dependent on Chinese battery suppliers, now is the time to rethink energy storage to ensure resilience in times of crisis.
