Simply as you’ve all the time suspected, the powers that be have been conserving an inexpensive miracle expertise from us—batteries could be made not from scarce and costly minerals, however from wooden!
Effectively, not precisely. However actually, lignin, a plant-derived polymer, is a renewable supply of carbon, and two European companies have launched a undertaking that goals to make use of lignin-based exhausting carbon produced from Nordic forest wooden as an anode materials.
Scandinavian forest product provider Stora Enso believes that “every thing that’s produced from fossil-based supplies right this moment could be produced from a tree tomorrow.” European battery producer Northvolt is on a mission to ship “the world’s greenest lithium-ion battery with a minimal CO2 footprint.”
The businesses have entered right into a Joint Improvement Settlement to create a sustainable battery that includes an anode produced from renewable uncooked supplies sourced sustainably and domestically in Nordic international locations.
Stora Enso will present its lignin-based anode materials Lignode, and Northvolt will present cell design, develop manufacturing processes, and scale up the expertise.
Stora Enso’s pilot plant for bio-based carbon supplies is situated on the its Sunila manufacturing web site in Finland, the place lignin has been industrially produced since 2015. The annual lignin manufacturing capability is 50,000 tons.
“The joint battery growth with Northvolt marks a step on our journey to serve the fast-growing battery market with renewable anode supplies produced from bushes,” says Johanna Hagelberg, Govt Vice President for Biomaterials at Stora Enso. “Our lignin-based exhausting carbon, Lignode, will safe the strategic European provide of anode uncooked materials, serving the sustainable battery wants for purposes from mobility to stationary vitality storage.”
“With this partnership, we’re exploring a brand new supply of sustainable uncooked materials and increasing the European battery worth chain, whereas additionally growing a cheaper battery chemistry,” says Emma Nehrenheim, Chief Environmental Officer at Northvolt.
