摘要
以聚丙烯腈,N、N-二甲基乙酰胺,γ-丁内酯和LiCIO_4为原料,配制了一系列具有离子导电性的固溶体。固溶体的离子电导率随盐浓度增加而单调增加,且离子电导率与温度之间呈VTF经验关系。循环伏安扫描结果表明固溶体的电化学稳定电压高于4.5V。
A series of solid composites with novel ionic conduction has been successfully prepared from polyacryloni-trile,N、N-dimethylacetamide,γ-butyrolactoue and lithium perchlorate. Ionic conductivity of the composites increases with dissolving salt into polymeric matrix and obeys VTF empirical equation based on free volume theory of amorphous polymers. Cyclic voltammogram shows the composite an electrochemical stability window of more
than 4. 5V vs. Li^+/Li.
