ORGANIC BATTERY USES POLYACETYLENE ELECTRODES

A lightweight, rechargeable organic storage battery that uses thin, stretchable film of polyacetylene instead of metal ions or free metal has been developed at the University of Pennsylvania, Philadelphia. Polyacetylene, normally a semiconductor, becomes, in effect, a metallic conductor when doped electrochemically. Thus, an electrochemical cell can be created by immersing two small pieces of polyacetylene film in a suitable electrolyte and connecting each film to one terminal of a dc power source. When immersed in a solution of tetrabutylammonium perchlorate in propylene carbonate, the polyacetylene strip serving as anode is oxidized and becomes doped with perchlorate anion; while the cathode strip is reduced and becomes doped with tetrabutylammonium cation. Because it is so lightweight and provides so much power e.g., 3.7 volts and 20 milliamps per sq cm of film), this type of battery is considered ideal for electric vehicles.
