Batteries with lignin from certified forests

A Finland-based company, experienced in developing wood- and biomass-based solutions for industry, has created a bio-based circular material that is used as an alternative to fossil carbon in lithium-ion batteries.
The material solution based on lignin, a byproduct of cellulose fiber production, is derived from forests certified for sustainable management. Lignin is a renewable and traceable material and already results as process waste that can be repurposed, enabling the rapidly growing battery industry to be sustainable.
Lignin by its nature gives wood rigidity and resistance to decomposition, it is refined into a fine carbon powder, which acts as an active material for the negative anode of the lithium-ion battery, then this is used to make electrode sheets and rolls, which combined with positive electrodes and other components create a lithium-ion battery.
