Electrochemical Investigations of the Interface at Li/Li+ Ion Conducting Channel (Supplemental)
Abstract
Studies were undertaken to examine the effect of substrate materials on impedance behaviour of lithium dipthalocyanine (Li2Pc). Several symmetrical cells were assembled using stainless steel (SS), gold foil, gold sputtered SS, copper, nickel and lithium electrodes. It was found that the Nyquist impedance spectrum obtained with SS electrodes consisted of two semicircles with total resistance of 1700 kOhm. But the cell with gold electrodes produced a single semicircle with resistance of 450 kOhm. Similarly, different values of impedance were obtained by varying the substrate materials. It was concluded that Li2Pc exhibits chemical reactivity with metallic substrates used in the study.
