Ion dynamics in lithium bismuth borate conducting glasses have been reported in wide composition and temperature ranges. The activation energy for the dc conduction has been analysed using Anderson-Stuart model and a correlation between the dc conductivity and the doorway radius has been predicted. The characteristic length scales for ion dynamics, such as mean square displacement and spatial extent of sub-diffusive motion of lithium ions have been determined from the ac conductivity and dielectric spectra, respectively. A direct connection between the ion dynamics and the characteristic length scales and the network structural units have been established.
在广泛的组成和温度范围内，已经报道了硼酸锂铋玻璃中的离子动力学。使用安德森-斯图尔特模型分析了直流传导的激活能，并预测了直流电导率与门口半径之间的相关性。从交流电导率和介电谱分别确定了锂离子的均方位移和亚扩散运动的空间范围等离子动力学的特征长度尺度。已经建立了离子动力学与特征长度尺度和网络结构单元之间的直接联系。
