Researchers at Linköping University's Laboratory of Organic Electronics, Sweden, have developed power paper -- a new material with an outstanding ability to store energy. The material consists of nanocellulose and a conductive polymer. The results have been published in Advanced Science.
One sheet, 15 centimetres in diameter and a few tenths of a millimetre thick can store as much as 1 F, which is similar to the supercapacitors currently on the market. The material can be recharged hundreds of times and each charge only takes a few seconds.
It's a dream product in a world where the increased use of renewable energy requires new methods for energy storage -- from summer to winter, from a windy day to a calm one, from a sunny day to one with heavy cloud cover.
"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," says Xavier Crispin, professor of organic electronics and co-author to the article just published in Advanced Science.
