研究了非晶态Ｌｉ２Ｏ－ＬｉＣｌ－Ｐ２Ｏ５－（Ａｌ２Ｏ３）和Ｌｉ２Ｏ－Ｐ２Ｏ５－Ｖ２Ｏ５系统晶化前期的Ｌｉ＋离子导电特性．两系统的Ｌｎ（σＴ）～１／Ｔ曲线上都有两个转折点：当Ｔ＜Ｔ１时，Ｌｎ（σＴ）～１／Ｔ满足Ａｒｒｈｅｎｉｕｓ的直线关系；而在Ｔ１～Ｔ２温度范围内电导率呈反常增加；当Ｔ＞Ｔ２时电导率又开始下降或越于平稳．用差热分析、扫描电镜、Ｘ镜线衍射技术对晶化前期（Ｔ１～Ｔ２）电导率反常增加现象进行了结构的初步探讨，认为是非晶样品分相及产生的微晶所致．
The Li + ion conductivity of amorphous Li2O-LiCl-P2O5- (Al2O3) and Li2O-P2O5-V2O5 system was studied. There are two turning points on the Ln (σT) ~ 1 / T curve of both systems: Ln (σT) ~ 1 / T satisfies the Arrhenius linear relationship when T T2, the conductivity began to decline or become more stable. Differential thermal analysis, scanning electron microscopy and X-ray diffraction were used to investigate the anomalous increase of conductivity in the early stage of crystallization (T1 ~ T2). It was considered that the phase separation and the microcrystals were caused by the amorphous phase.
