【 摘 要 】

Cells of lithium ion conducting glassy electrolyte Li₂SO₄â€�?�Li₂Oâ€�?�B₂O₃ with different combinations of electrodes (stainless steel blocking electrode, lithium non-blocking electrode and TiS₂ electrode) have been prepared. The a.c. impedance measurements of the cells have been studied at elevated temperature as a function of time. The circuit elements such as bulk resistance, double layer capacitance and charge transfer resistance have been inferred and their time dependence studied. The results show that the electrolyte and the interface are chemically very stable with the different types of electrodes studied here.
