Аннотация
Electrochemical Methods were used to study the Pt|Li0.9CoO2|(Li7La3Zr2O12 + LiPO3 glass)|Li0.9CoO2|Pt symmetric cell simulating the operation of the cathode of a solid-state power cell. It was shown that the glassy electrolyte serves in the system for organizing an ionic contact between the solid electrolyte and the cathode material. The current-breaking method and impedance spectroscopy demonstrated that the resistance of the cell is about 600 Ω at a temperature of 325°C. The overvoltage is 88 mV at a current density of 13 µA cm–2. The plot describing the dependence of the current density on voltage is of the activation type, i.e., the main contribution to the polarization comes from the activation component.
