Paper-Based Thin-Film Batteries

Technology Review - Published By MIT
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.

Ultrafast All-Polymer Paper-Based Batteries

Abstract Image

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).
