BillerudKorsnäs and researchers at Uppsala University in Sweden have together taken an important step towards the future’s paper batteries. Together they have taken basic research based on pure cellulose from algae and developed it to work with the same type of fibre 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.
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. 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. 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.
