近年来，许多新型的具有高Li+电导率的玻璃基固体电解质被开发出来。本文综述了提高Li+电导率的两种策略：利用硫化物和氧阴离子的“混合阴离子效应”和通过对玻璃进行仔细的热处理沉淀超离子亚稳晶体，在此基础上制备和表征了Li 2S基氧硫玻璃和硫化物玻璃陶瓷。在Li_2S-P_2S_5微晶玻璃中获得了具有最高电导率和最低导电活化能的上级Li ~+导电固体电解质。这些玻璃陶瓷固体电解质的使用导致具有优异循环性能的块型全固态锂二次电池的开发。(c)2006 Elsevier B. V.保留所有权利。
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.
