A Swedish university and paper manufacturer are working together to create batteries made of paper. BillerudKorsnäs, a Swedish paper manufacturer, collaborated with Uppsala University professor’s Maria Strömme and Albert Mihranyan to develop the paper batteries. The technology involves placing energy storage inside of fibre structures using compounds that conduct organic polymers.

The end goal is to hopefully be able to mass produce the paper batteries for smart packaging applications. The potential applications could involve real-time temperature gauges or parcel tracking, allowing users the ability to track a specific parcel in real time or even help to find a package if it has been missed placed. The batteries will be able to be fully recyclable as part of BilerudKorsnäs' pledge to a more sustainable future.
