A note on the impedance response of Li/LiCl/solid electrode system
The influence of solid electrodes such as lithium, platinum and conductive paints (silver print and conductive carbon cement) on the overall impedance response of a Li(parent electrode)/LiCl(polycrystalline)/solid electrode system is reported. The impedance response is measured as a function of d.c. voltage bias. The observed changes in impedance spectra are compared to the corresponding measurements in systems involving liquid solutions (lithium batteries) as given in literature. The contribution of poor contact at the LiCl/solid electrode interface and the porosity of the LiCl film to the measured impedance response is discussed.
