Abstract: | The objective of this work was to study field-induced silver injection into Li2O · 2SiO2 glass by the techniques of secondary ion mass spectrometry and thermally stimulated polarization/depolarization current (TSPC/TSDC), with an emphasis on the comparison experiments between gold and silver electrodes. For both anode materials, accumulation of lithium was found near the cathode. The blocking nature of the gold anode was demonstrated by the closeness of the observed and estimated width of the alkali-depleted region near the anode. For silver-anode samples, field-induced silver injection as well as lithium conduction occured and increased the TSPC slope from that of the gold-anode samples. |
