Northvolt partners with Stora Enso to develop wood-based batteries.

Lignin produced from trees will be used to make the anode of the wood-based batteries.

Swedish battery manufacturer, Northvolt announced that it has partnered with Stora Enso to develop wood-based batteries. Stora Enso is a provider of renewable products in packaging, biomaterials, wooden construction, and paper and is one of the largest private forest owners in the world.

Both companies are collaborating to create sustainable batteries using lignin-based hard carbon produced from wood. The goal of this partnership is to build the greenest battery in the world with a minimal carbon footprint.

The anode of the wood-based battery would be produced from the lignin-based anode material known as Lignode.

Lignin is a plant-derived polymer found in the cell walls of dry-land plants. Trees are composed of 20–30% of lignin, which acts as a natural and strong binder. It is one of the biggest renewable sources of carbon anywhere.

As per the tie-up, Stora Enso will provide its lignin-based anode material Lignode, originating from sustainably managed forests, while Northvolt will drive cell design, production process development, and scale-up of the technology.

Stora Enso produces around 50,000 tonnes of lignin at its production site in Finland.

Johanna Hagelberg, Executive Vice President for Biomaterials at Stora Enso, said: The joint battery development with Northvolt marks a step on our journey to serve the fast-growing battery market with renewable anode materials made from trees. Our lignin-based hard carbon, Lignode® by Stora Enso, will secure the strategic European supply of anode raw material, serving the sustainable battery needs for applications from mobility to stationary energy storage.

Emma Nehrenheim, Chief Environmental Officer at Northvolt, said: With this partnership, we are exploring a new source of sustainable raw material and expanding the European battery value chain, while also developing less expensive battery chemistry. It is an exciting demonstration of how our pursuit of a sustainable battery industry goes hand-in-hand with creating a positive impact both on society and cost.
