Altris AB is a Swedish battery materials and technology company focused on sodium‑ion energy storage. The company develops and produces Prussian White–based cathode materials (sodium iron hexacyanoferrate), as well as electrolytes, cell designs, and processes to industrialize sodium‑ion battery manufacturing. Its chemistry uses abundant, non‑critical elements such as sodium and iron, offering an alternative to lithium‑ and cobalt‑based systems.
Altris targets safe, recyclable, and cost‑efficient batteries for applications including stationary energy storage and selected mobility segments. The company works with industrial partners to integrate its materials into commercial cells and to scale production for broader deployment of sodium‑ion technologies.
