Altris is a Swedish battery materials company specializing in sodium‑ion technology. The company develops and produces cathode active materials based on Prussian White chemistry (sodium iron hexacyanoferrate), commonly known under its Fennac brand, and works on complementary electrolytes and cell engineering to enable industrial deployment.
Altris focuses on scalable processes that use abundant, non‑critical and non‑toxic elements. Its technology targets applications where safety, cost and resource availability are central, including stationary energy storage and low‑voltage automotive and industrial systems. The company supports customers from material qualification through cell development and manufacturing scale‑up, contributing to the build‑out of a European supply chain for sodium‑ion batteries.
