Paper-Based Thin-Film Batteries

clipped from www.technologyreview.com A Salt and Paper Battery The simple, non-polluting battery could be used in compact devices. Researchers at Uppsala University in Sweden have made a flexible battery using two common, cheap ingredients: cellulose and salt. The lightweight, rechargeable battery uses thin pieces of paper--pressed mats of tangled cellulose fibers--for electrodes, while a salt solution acts as the electrolyte. clipped from pubs.acs.org Ultrafast All-Polymer Paper-Based Batteries clipped from www.altdotenergy.com The key to the discovery lies in the way in which the algae, Cladophora, produce a unique type of cellulose with a very large surface area (approximately 80 square meters of surface area per gram of material). clipped from personal.teknik.uu.se Nanotechnology and Functional Materials Welcome to the division for Nanotechnology and Functional Materials. We are a part of the Department for Engineering sciences and situated at the Ångström Laboratory. The division was established in 2004 and is headed by prof. Maria Strømme.
