摘要
本文采用光电子能谱分析方法,首次研究Li_2S-SiS_2-LiBO_2-LiCl体系硫氧化物玻璃锂离子导体的组成、结构和状态。指出在该玻璃体系中,除与硅(硼)相键合的桥硫存在外,还有不与硅(硼)相键合的非桥硫存在;玻璃中的硫取代了氧的位置,进入玻璃网络中使结构紧密交联。对网络中的元素状态,成键及性能进行了讨论。
The composition, structure and state of oxysulfide glassy lithium ion conductors for Li_2S-SiS_2-LiBO_2-LiCl system were studied by means of XPS.The result of XPS shows that in the glass, the partial sulfur atoms replaced oxygen place in glassy bond with boron atoms and exist in the form of bridging sulfur to produce a more highly cross-linked and stable glass network. The elements state in the glass network and bonding mechanism were discussed.
