## About

Altris AB, founded in 2017 in Uppsala, Sweden, focuses on the development of sodium-ion batteries. The company has undergone no significant pivots, and it operates independently without subsidiaries. The founder, William Brant, has a history in technology innovation. In October 2025, Altris AB raised SEK 80.75 million in venture funding from InnoEnergy.
Altris specializes in sodium-ion battery technology, producing cathodes, electrolytes, and cell designs aimed at mass-market applications. Their products utilize abundant materials like salt and iron to minimize environmental impact, targeting low-voltage mobile applications, energy storage, and maritime sectors. Altris primarily serves markets in Europe and North America, with an expanding interest in global markets focused on sustainable energy solutions.
