‘Power paper’ made from organic materials, stores electricity by conducting ions and electrons.
Researchers at Linköping University‘s Laboratory of Organic Electronics, Sweden, developed the power paper, a new material with an outstanding ability to store energy, consisting of nanocellulose and a conductive polymer.

On one 15 centimeters in diameter sheet and a few tenths of a millimeter thick, can store as much energy as to the supercapacitors currently on the market, can be recharged hundreds of times, that only takes a few seconds.
Considered as a ‘dream product,’ in a world where the increased use of renewable energy requires new methods for energy storage.
Xavier Crispin, professor of organic electronics and co author, said:
“Thin films that function as capacitors have existed for some time. What we have done is to produce the material in three dimensions. We can produce thick sheets.”
