The new material stored energy and can be bent. Swedish researchers from Linköping University have created a material with exceptional ability to store electricity. Scientists call its development "Energy Charter". The material consists of cellulose nanofibers, and a conductive polymer. One such piece of paper with a diameter of 15 cm and a thickness not less than 1 mm has a capacity of 1 Farad - comparable to the capacity of yonistorite available today on the market.
