The Kinetics of the Lithium Electrode during the Discharge of Li / SOCl2 Cells
Résumé
The kinetics of the anodic dissolution of lithium has been investigated by means of polarization curves and impedance plots measured during the discharge of cells containing various electrolytes. A voltage delay appears for lithium electrodes characterized by a low frequency inductive impedance and a bell‐shaped polarization curve, thus suggesting a conduction‐controlled charge transfer through an film whose conductance depends on anodic potential. By changing the electrolyte composition, the voltage delay can be canceled and the charge transfer through the film becomes diffusion controlled. A change in the film properties is observed during the storage of cells.
