Title:
LITHIUM ION CONDUCTOR MATERIAL, SYNTHESIS METHOD THEREFOR, AND SECONDARY BATTERY
Document Type and Number:
WIPO Patent Application WO/2019/130923
Kind Code:
A1
Abstract:
This lithium ion conductor material is expressed by the composition formula M0.5-xLiyTa1-zTizO3, and when the element denoted by M includes at least Sr from among Sr and La, x is in a range of x = 0.03 to 0.05, and x and y satisfy (y-x)<0.5. A perovskite-type lithium ion conductor material of such a composition exhibits very high bulk ion conductivity at room temperature.
