摘要：

In recent years many new glass-based solid electrolytes with high Li+ conductivity have been developed. In the present paper, we review the preparation and characterization of Li2S-based oxysulfide glasses and sulfide glass-ceramics on the basis of two strategies of enhancing Li+ conductivity: the utilization of "mixed-anion effect" by combining sulfide and oxide anions, and the precipitation of superionic metastable crystals by careful heat-treatment of glasses. The superior Li+ conducting solid electrolytes with the highest conductivity and the lowest activation energy for conduction have been achieved in the Li2S-P2S5 glass-ceramics. The use of these glass-ceramic solid electrolytes leads to the development of a bulk-type all solid-state lithium secondary battery with excellent cycling performance. (c) 2006 Elsevier B.V.
