At first sight it seems paper, touching plastic: it is a material composed of a conductive polymer and nano-cellulose that can be made in sheets of very thin layer (thickness less than 0.5 mm and a diameter of 15 centimeters), black. The real peculiarity? This material is capable of storing an electrical capacity of 1 farad, a capacity very close to several super capacitors installed in the electrical and electronic devices.
It could be a revolution for storage in small devices, including aspects “green”: it is a material made from simple materials and without metal. The real challenge will be to develop a large-scale production which has costs and reasonable processes.
The invention comes from the joint research of scientists in Sweden (Linköping University and KTH Royal Institute of Technology), Danish (Technical University of Denmark) and American (University of Kentucky).
