A new kind of paper has the remarkable ability to store energy like a supercapacitor. It comes from researchers at Sweden’s Linköping University’s Laboratory of Organic Electronics and it has the potential to turn a new chapter for renewable energy.

The so-called "power paper" was made from cellulose fibers that were subjected to high-pressure water until they broke down into fibers as thin as 20 nanometers in diameter. Next, the fibers were coated in an electrically charged polymer and fashioned into a round sheet.

Each sheet, which is 15 centimeters in diameter and a few tenths of a millimeter thick can store as much as supercapacitors currently available on the market. The material can be recharged hundreds of times and each charge only takes a few seconds.
