BillerudKorsnäs and researchers at Uppsala University have together taken an important step towards paper batteries. Together they have taken basic research based on pure
cellulose from algae and developed it to work with the same type of fiberthat 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.
The development work is being carried out by one of Sweden’s foremost research teams under Maria Strömme, collaborating with BillerudKorsnäs, as a leading company in the development of sustainable packaging technology, in a completely new form.
“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,” says Lars Sandberg, project manager for innovation at BillerudKorsnäs.
Smart, connected packaging
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 new products that can be traced through the entire transport chain. This includes, for example, packaging that measures temperature or position in real time and provides information on what is happening with an item during transport.
For example, a light sensor along with a BillerudKorsnäs paper battery could provide information on where in the transport chain a product disappeared from its packaging. With electrodes based on cellulose from wood fiber, the ambition is that in the future, it will be possible to recycle batteries along with their boxes and make them into new boxes or paper batteries.
