Altris AB, founded in 2017 in Uppsala, Sweden, specializes in developing and manufacturing sodium-ion battery technology. The company creates sustainable energy storage solutions using abundant raw materials like salt, wood, iron, and air. Their innovative approach to battery production addresses critical environmental concerns while maintaining high performance standards. As a leading Swedish developer in this field, Altris focuses on producing batteries that combine efficiency with environmental responsibility, aiming to establish itself as Europe’s primary sodium-ion battery developer. Their commitment to sustainability and performance has positioned them as a significant contributor to the evolution of energy storage technology.
Battery Technology
The company’s core technology centers on their proprietary cathode material, Fennac, and the newer Altris Prussian White. These materials achieve an impressive energy density of 160 Wh/kg, matching or exceeding traditional lithium iron phosphate (LFP) batteries. The sodium-ion batteries developed by Altris offer several advantages:
- Enhanced safety features and extended lifecycle
- Flexible operating temperatures
- Superior power performance
- Sustainable production using readily available materials
- Compatibility with existing lithium-ion manufacturing facilities
Their patented manufacturing process ensures consistent quality while minimizing energy consumption. The technology allows for production in standard facilities without requiring specialized dry rooms, significantly reducing setup and operational costs. Altris’s batteries serve various applications, from grid storage to commercial transportation, offering particular benefits in low-voltage automotive systems and renewable energy storage solutions.
The company maintains its research and development activities at the Uppsala headquarters while expanding manufacturing operations through the Ferrum facility in Sandviken.
Recent Projects
In October 2024, Altris completed a significant Series B1 funding round, securing SEK 150 million to enhance their production capabilities. The company has established a collaboration with Clarios to develop low-voltage sodium-ion batteries for automotive applications. Their pilot production facility, Ferrum, located in Sandviken, Sweden, is advancing toward full operation with an annual capacity of 2,000 metric tonnes of cathode material, enabling the production of 1 GWh of batteries per year. Additionally, Altris has partnered with Polarium to create innovative energy storage solutions based on their sodium-ion technology.
Investors
Altris has attracted investment from prominent industry players and venture capital firms. The investor base includes:
- EIT InnoEnergy: An established energy innovation investor
- Molindo: A long-term financial partner
- Clarios: A global battery technology company that joined during the Series B1 round
- Maersk Growth: The venture arm of A.P. Moller – Maersk, which invested in the latest funding round
These strategic partnerships provide not only financial support but also valuable industry expertise and market access opportunities.
