High Lithium Ion Conductivity of Glass-Ceramics Derived from Mechanically Milled Glassy Powders
Crystallization of the 80Li2S·20P2S5 (mol%) glassy powders derived from mechanical milling improved their conductivities. The obtained glass–ceramic exhibited high conductivity of approximately 10−3 S cm−1 at room temperature. The stabilization of the high-temperature phase of Li7PS6 crystal in the glass matrix brought about those high conductivities.
