The characteristics of the electrochemical doping process of polyacetylene have been investigated in lithium cells using lithium perchlorate in propylene carbonate as the electrolytic solution. The kinetics of this process are controlled by the diffusion of the dopant species throughout the polymer.

✦ Synopsis
The morphology, electrical and electrochemical properties of two types of polyacetylenes (powder form and electrophoretically deposited films) were studied and their behaviour compared. Their function as positive electrode in Li cells was studied by means of cyclic voltammetry and electrochemical impedance measurements . The maximum coulombic capacity of the pressed powder form was 80 Ah kg -' . The performance of the cell was limited by diffusion of anions into the polyacetylenc structure. The electrophoretically deposited films were electrochemically inactive .

Poly(phenyl vinyl sulfoxide) (PVSO) is a soluble precursor to polyacetylene (PA). Upon thermal elimination, the thermally labile PVSO can be converted to PA by undergoing a 'zipper-like' 5-members cyclic sigmatropic elimination process. Both PVSO and its copolymers can be synthesized via anionic pol
