High Lithium Ion Conductivity of Glass-Ceramics Derived from Mechanically Milled Glassy Powders

摘要

Crystallization of the 80Li_2S·20P_2S_5 (mol%) glassy powders derived from mechanical milling improved their conductivities. The obtained glass-ceramic exhbiited high conductivity of approximately 10~(-3) S cm~(-1) at room temperature. The stabilization of the high-temperature phase of Li_7PS_6 crystal in the glass matrix brought about those high conductivities.
