What Altris does
Altris AB is a Swedish sodium-ion battery technology company founded in 2017 and headquartered in Uppsala, spun out of Uppsala University's Ångström Laboratory. It develops a proprietary Prussian White cathode material produced via a patented low-temperature, ambient-pressure synthesis route (achieving 160 mAh/g capacity, the highest declared for abundant-material-based Prussian White), a patented NaBOB inherently fire-resistant electrolyte, and finished sodium-ion battery cells. Its products are made from globally abundant raw materials — salt, wood, iron, and air — without lithium, cobalt, nickel, or copper, and are designed to be manufacturable inside existing lithium-ion factories, lowering adoption friction. The company has demonstrated a commercial-sized cell with 160 Wh/kg energy density, on par with LFP, validated in research with Northvolt, and operates across a temperature range of roughly -40°C to +70°C with strong cold-start capability.

Revenue model
- Cathode Material Sales (Fennac/Prussian White): Altris sells its proprietary cathode material Fennac to battery-cell producers. Manufacturers can use existing lithium-ion production equipment to produce Fennac-based batteries, creating a straightforward adoption pathway. This is the primary revenue stream.
- Commercial Battery Cells: The company offers commercial battery cells for select niche applications, selling finished sodium-ion battery products directly to customers requiring complete battery solutions.
- Technology Licensing and Factory Blueprints: Altris licenses sodium-ion battery designs and provides production blueprints to manufacturers, enabling third parties to produce batteries using Altris' technology. This creates recurring licensing revenue while reducing capital requirements for scaling.
- Joint Development Agreements: Revenue from formalized development agreements with partners like Clarios, where Altris provides sodium-ion cell technology expertise while partners contribute development funding and commercialization infrastructure.

Altris competitors and assessment
Company assessmentDirect peers
- Natron Energy: US/Netherlands-headquartered sodium-ion battery developer using Prussian Blue analogue cathode chemistry — virtually the same core material strategy as Altris's Prussian White. Targets stationary storage and data center backup, directly competing for the same Western sodium-ion ESS opportunity.
- Faradion: UK-based sodium-ion battery pioneer (acquired by Reliance Industries in 2022) developing sodium-ion cells for mobility and stationary storage. One of the longest-standing Western sodium-ion developers and a direct peer in technology, geography, and target market.
- Tiamat: French sodium-ion battery developer spun out of CNRS, building 18650-format sodium-ion cells for power tools and mobility. Closely comparable to Altris as a European sodium-ion cell-focused company with similar cell-format and application ambitions.
- HiNa Battery Technology: Chinese sodium-ion battery company spun off from the Institute of Chemistry of the Chinese Academy of Sciences; operates one of the earliest commercial sodium-ion cell lines. Direct global sodium-ion peer and a key cost/scale benchmark for Western players including Altris.
Broad incumbents
- CATL: World's largest battery manufacturer, which has already launched sodium-ion product lines (e.g., Naxtra) for automotive and stationary storage. Represents the dominant scaled competitor whose cost base and manufacturing capacity set the floor Altris must compete against.
- BYD: Chinese battery and EV giant with publicly disclosed sodium-ion R&D and product roadmap. Overlaps with Altris in automotive low-voltage and stationary storage ambitions at vastly larger scale and lower cost.
- Northvolt: Swedish battery manufacturer that was an early Altris investor and partner — the partnership validated Altris's 160 Wh/kg cell. Currently undergoing severe financial restructuring, but remains a relevant peer in European battery materials and cell manufacturing.
- Clarios: Global leader in low-voltage automotive batteries. As Altris's core commercialization partner via the Power Sodium JDA, Clarios is both a customer and a peer in low-voltage automotive energy storage and brings deep OEM relationships Altris leverages.
Emerging players
- ESS Inc: US long-duration iron flow battery company targeting grid-scale stationary storage. Adjacent competitor to Altris's sodium-ion grid storage offering, particularly for applications where cost-per-kWh-cycle matters more than energy density.
- Form Energy: US iron-air battery developer focused on multi-day grid storage. Competes with Altris for stationary-storage capital and utility customers, though with a different chemistry profile targeting 100+ hour duration.
