Abstract

Kinetic parameters for solid lithium electrodes have been evaluated at for in propylene carbonate at several concentrations between 0.1 and 1.0M. Polarization data obtained by the interrupted current method agree with that obtained by a pulse technique. Depending on its treatment, the electrode exhibits one of two levels of activity. This phenomenon is believed to be due to the presence of a film formed by reaction between lithium metal and the solvent or impurities. The film is broken down at higher current densities, effecting an increase in electrode area. The area increase has been corroborated by double‐layer capacitance measurements. Standard exchange current of a film‐free electrode in is .
