Power paper is a new material with outstanding ability to store energy. It consists of nanocellulose and a conductive polymer. 1 sheet, 15 cm in diameter and a few tenths of a mm thick can store as much as 1F, 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 3D...
