Electrochemical cell Li–Ga–Ag | Li₇La₃Zr₂O₁₂ + 5 wt % 40.2Li₂O·5.7Y₂O₃·54.1SiO₂ glass | 25Li₂O·30B₂O₃·45V₂O₅ glass ceramic was studied. The glassy materials 40.2Li₂O·5.7Y₂O₃·54.1SiO₂ and 25Li₂O·30B₂O₃·45V₂O₅ were produced by melt quenching. The use of a glassy cathode based on vanadium oxide enabled a close contact between the cathode and the solid electrolyte. At a temperature of 280°C, the electrochemical cell under study can be charged to 3.33 V. It was found that the deintercalation of lithium is hindered in the course of charging and discharge.
