文摘

The La_0.56Li_0.33TiO₃ ceramic with the structure of defect perovskite and high conductivity of (2-4) × 10- S cm- at the room temperature is obtained. Ceramic electrolyte based on La_0.56Li_0.33TiO₃ is developed for a lithium–air cell with EMF of 3.1 V and high discharge stability in time. Discharge characteristics of a lithium–air cell are studied in a laboratory cell. The dependence of electrophysical properties of a lithium–air cell on the thickness of the La_0.56Li_0.33TiO₃ ceramic electrolyte and effect of the catalyst on its discharge characteristics are investigated. Keywords lithium–air cell perovskite La_0.56Li_0.33TiO₃ lithium conductivity ceramic electrolyte discharge curves
