Résumé

The conducting polymers like (CH)x are very interesting materials for electrodes in electrochemical cells. We have combined such electrodes with solid electrolytes to build "all solid-state" batteries. The first prototypes using a silver anode and a silver conducting electrolyte have been working satisfactorily since two years. The performances have been tested with many batteries to study the electrical properties as well as the thermodynamical parameters. A number of cycles of charge-discharge have been recorded at various values of the current kept constant. This has allowed to determine the essential properties : voltage, current, current density, reliability, Faradaic and energetic efficiency ... The performances have also been investigated as a function of temperature, allowing to derive the enthalpy and the entropy of the electrochemical reaction. The kinetics of the discharge has been thorough-fully measured and compared to the mass transport data recently obtained in our laboratory by using radiotracers. This has given a clear explanation of the mechanism of mass transport inside the polymer.
