High lithium ion conductivity of glass-ceramics derived from mechanically milled glassy powders
Crystallization of the 80Li(2)S . 20P(2)S(5) (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.
