Altris’s core technology uses proprietary cathode materials Fennac and Altris Prussian White, achieving 160 Wh/kg energy density, matching or exceeding lithium iron phosphate (LFP) batteries. Their sodium-ion batteries offer enhanced safety, extended lifecycle, flexible operating temperatures, superior power, sustainable production with abundant materials, and compatibility with existing lithium-ion manufacturing. Their patented manufacturing reduces energy use and operates in standard facilities without specialized dry rooms, cutting costs.
They produce sodium-ion batteries suited for grid storage, commercial transportation, low-voltage automotive systems, and renewable energy storage. The Ferrum facility in Sandviken advances production with a capacity of 2,000 metric tonnes of cathode material annually, producing 1 GWh of batteries per year.
Notable projects include a 2025 collaboration and investment agreement with Volvo Cars for battery energy storage system (BESS) development, a joint development partnership with Clarios for low-voltage automotive sodium-ion batteries, a collaboration with Polarium on non-toxic sodium-ion energy storage solutions, and a partnership with Stora Enso to develop hard carbon anode materials. Altris completed a SEK 150 million Series B1 funding in 2024 to expand production, supported by the Swedish Energy Agency and recognized with the 2024 EIT Innovation Team Award.
Investors in Altris AB include EIT InnoEnergy, Molindo, Clarios International Inc., Maersk Growth, and Volvo Cars Tech Fund. In 2024, the company raised SEK 150M in a Series B1 funding round led by Clarios International Inc., Maersk Growth, and Volvo Cars Tech Fund, alongside existing shareholders. The Swedish Energy Agency also provides financial support for pilot plant development.
