Lithium-air cell with lanthanum-lithium titanate ceramic electrolyte

摘要

The La0.56Li0.33TiO3 ceramic with the structure of defect perovskite and high conductivity of (2-4) x 10(-3) S cm(-1) at the room temperature is obtained. Ceramic electrolyte based on La0.56Li0.33TiO3 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 La0.56Li0.33TiO3 ceramic electrolyte and effect of the catalyst on its discharge characteristics are investigated.
