✦ Synopsis

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. Therefore, polyacetylene samples with a highly porous, extended surface should be selected for the development of efficient, rechargeable lithium batteries. In line with this, we have considered foam-type polyacetylene electrodes which have a lower density than the 'classical' Shirakawatype film electrodes. The electrochemical behaviour of the polyacetylene foam samples has been examined by cyclic voltammetry response and constant current, charge-discharge cycles. The results are described in this work.
