In Sweden, BillerudKorsnäs and Uppsala University are making paper batteries a reality, paving the way for energy storage in packaging materials. They took basic research based on pure cellulose from algae and developed it to work with the same type of fiber that BillerudKorsnäs usually uses to manufacture packaging material. This development opens up for both inexpensive and eco-friendly batteries. The long-term aim is to enable large-scale production and the future use of paper batteries for applications in areas such as smart packaging.
“What’s special in this case is the model for collaboration between BillerudKorsnäs and Uppsala University that has resulted in technology adapted to large-scale production processes. We’re combining the deep theoretical expertise of the researchers with our understanding of innovation and production technology. By successfully creating a joint platform, we can focus our work on the future, on creating an advanced product that can still be produced in an effective way,” says Lars Sandberg, project manager for innovation at BillerudKorsnäs.
In the long term, the paper battery opens up possibilities for developing packaging that is both smart and more sustainable. Small paper batteries with sensors can in the future open up for packaging that can be traced through the entire transport chain.
