Altris, Stora Enso team up to use lignin in sodium-ion batteries

Swedish sodium-ion battery developer Altris and Finnish pulp and paper maker Stora Enso Oyj (HEL:STERV) have teamed up to adapt Stora Enso’s hard carbon material, called Lignode, as an anode material in Altris’ sodium-ion battery cells.

The partnership, announced today, will combine Altris’ sodium-ion battery technology and its Prussian White cathode material with Stora Enso’s anode solution Lignode, with the goal of strengthening the development of sustainably sourced batteries and supporting a European battery supply chain. Lignode is derived from lignin, a by-product from the manufacturing of pulp.

As the partnership evolves over the coming years, the companies will aim to commercialise the world’s most sustainable battery, said Altris CEO Bjorn Marlid.

“At Altris, we strive to establish a local supply chain and leverage abundant and clean materials to develop sodium-ion batteries. Therefore, it’s exciting to team up with Stora Enso and take part in their establishment of a Europe-based tree-to-anode supply chain,” Marlid commented.
