摘要
制备了含WO_3的钨磷酸盐非晶锂离子导体。采用红外(IR)光谱和拉曼(Raman)光谱研究了样品的结构,认为样品的玻璃网络结构主要是由[PO_4]和[WO_4]两种四面体基团连接而成的。测量了样品的密度和电导率。讨论了组成、结构与性能的关系。
The lithum-tungsten-phosphate non-crystalline ionic conductors are prepared. The struc- ture of sample is studied by IR and Raman spectra. It is determined that the structure network is constituted by linking of [PO_4] and [WO_4] tetrahedras. The density and conductivity of sample are measured. And the relationships of composition,structure and conductivity are discussed.
