Linköping University’s Laboratory of Organic Electronics in Sweden has developed a type of power paper that is capable of storing as much as 1 F of electricity in a single sheet which is 15 cms in diameter and the fraction of a millimetre in thickness. It is possible to charge the paper hundreds of times, with each charge lasting not more than a couple of seconds.

The paper requires nothing more than renewable cellulose and an easily available polymer as its components. The polymer-cellulose material simultaneously conducts both ions and electrons, thereby setting a world record with this kind of conduction activity. This attribute of the material also allows it to have [...]
