瑞典Altris了sc€9.6(100瑞典克朗)ale up production of its environmentally-friendly cathode material for rechargeable sodium batteries.

The Series A funding round will scale up production of the material, called Fennac, to 2,000 tonnes, enabling 1 GWh of sustainable batteries and further research and development of sodium-ion batteries to take place.

Fennac is a high performance sodium-ion cathode material made from entirely sustainable and low-cost materials that are available in abundance, without any cobalt, nickel or copper. The cost of all these materials is increasing as a result of supply chain worries.

The high sodium content Prussian White powder (Na_xFe[Fe(CN)₆] with x>1.9) can be paired against anode materials which do not contain sodium. Ideal storage is under inert conditions in order to maintain quality over the longer term and operates at a nominal voltage of 3.25 V on average with a capacity around 160 mAh/g.

Altris, based in Uppsala, also uses an innovative and patented manufacturing method for Fennac that is low-cost and more environmentally friendly compared to the alternatives.

• €5m for production of sodium battery cells for electric cars
• Polymer cathode for sodium battery designs

“With our new financial backing we stand ready to provide customers with the knowledge and materials they need to fulfil their sodium-ion battery aspirations, at a time where interest in this technology has never been greater” said Adam Dahlquist, CEO of Altris. “Our new industrial manufacturing unit will ensure that Fennac-based batteries become a reality within 2 years.”
