摘要：

A lithium-ion highly conductive new crystal was first precipitated in the Li2S-P2S5 glass-ceramics obtained by crystallization of the glasses. The 70Li(2)S center dot 30P(2)S(5) (mol %) glass-ceramic heated at 360 degrees C showed the highest conductivity of 3.2 X 10(-3) S cm(-1) at room temperature and the lowest activation energy of 12 kJ mol(-1) for conduction. The new crystal was formed by heat-treatment from 240 to 360 degrees C, and the Li4P2S6 crystal was present at 550 degrees C, indicating that the new crystal was precipitated as a metastable phase. The superionic metastable phase is responsible for the high conductivity and low activation energy of the glass-ceramics. (c) 2005 The Electrochemical Society.
