New lithium ion conductor, thio-LISICON lithium zirconium sulfide system

摘要：

A new lithium ion conductor, thio-LISICON (Lithium SuperIonic CONductor), Li2ZrS3 was synthesized by solid state reaction. It has the lithium ion conductivity of 7.3×10-6 S cm-1 at 30℃. Its conductivity were successfully improved by introducing interstitial lithium ions with Zr4+partially substituted by Zn2+(Li2+2xZnxZr1-xS3; x=0, 0.05, 0.1, 0.2, 0.4). The optimum x value for introducing the highest content of interstitial lithium ions was found to be 0.1. And the highest ionic conductivity at 30℃ was reached to be 1.2×10-4 S cm-1.
