对两种非晶态B_2O_3-0.7Li_2O-0.7LiCl-xAl_2O_3-0.1V_2O_5(x=0.05和0.15),用差热分析、电导率测量、X射线衍射和电子自旋共振进行研究,发现:1)V_2O_5不仅作非晶网络形成剂,而且改变了晶化过程;2)对B_2O_3-Li_2O-LiCl-Al_2O_3-V_2O_5玻璃,与P_2O_5-Li_2O-LiCl-Al_2O_3玻璃类似,粉末压片的离子电导率比60目粉末大26倍,而整片非晶的离子电导率又比粉末压片大近二个数量级,而且激活能明显减小,更适合离子传输;3)添加少于3.9mol%的V_2O_5,对非晶态锂离子导体B_2O_3-0.7Li_2O-0.7LiCl-xAl_2O_3,未引起电子电导率显著增大,又可应用电子自旋共振(ESR)技术研究其微观结构和电子运动状态。
Differential thermal analysis, conductivity measurement, X-ray diffraction and electron spin resonance of two kinds of amorphous B 2 O 3-0.7Li 2 O-0.7LiCl-xAl 2 O 3-0.1V 2 O 5 (x = 0.05 and 0.15) V2O5 not only makes amorphous network forming agent but also changes the crystallization process. 2) For B2O3-Li2O-LiCl-Al2O3-V2O5 glass, similar to P2O5-Li2O-LiCl-Al2O2O3 glass, The powder is 26 times larger, while the bulk amorphous ion conductivity is about two orders of magnitude larger than that of powder compaction, and the activation energy is obviously reduced, which is more suitable for ion transport. 3) Adding less than 3.9 mol% V 2 O 5, The amorphous lithium ion conductor B_2O_3-0.7Li_2O-0.7LiCl-xAl_2O_3 did not cause a significant increase in electron conductivity, but also the electron spin resonance (ESR) technique was used to study the microstructure and electron motion.
