Companies worldwide are working on a sustainable power storage solution using renewable biowaste called lignin to make wood batteries.
One of the largest private forest owners in the world, Stora Enso, recently built a production facility worth €10 million to create bio-based carbon by turning trees into batteries.
Producing these wood batteries is possible by using a biomaterial known as lignin.
How Lignin is Made to Create Wood Batteries
Lignin is one of the most common organic polymers, second to cellulose, that’s abundant in the cell walls of some plants. It makes the structure of the plant firm and doesn’t easily rot.
This biomaterial makes up about 30% of the wood’s total composition. In fact, it’s present in all vascular plants and can have a carbon content as high as 60%.
Lignin separates from wood during the production of cellulose fibers from its pulp. After…
