Today, fossil-based carbon is used in the anodes of rechargeable batteries. By converting lignin separated from wood into carbon-based anode materials, the synthetic and non-renewable graphite material can be replaced.The global battery market is projected to grow tenfold over the next decade as battery producers seek more sustainable materials for the electrification of mobility.
“With Lignode, we can provide a bio-based, cost-competitive and high-performance material to replace the conventionally used graphite. To serve the fast-growing anode materials market, we are now exploring strategic partnerships to accelerate scale-up and commercialisation in Europe,” says Markus Mannström, Executive Vice President of Stora Enso’s Biomaterials division.
The pilot plant for bio-based carbon materials is located at Stora Enso’s Sunila production site in Finland. The biorefinery’s annual lignin production capacity is 50 000 tonnes, making Stora Enso the largest kraft lignin producer in the world.
