摘要： 用不同分子量聚乙二醇和二氯甲烷在氢氧化钾存在下合成几种氧亚甲基连接的聚氧乙烯多嵌段聚合物。某些聚合物具有较好的力学性能和一定的结晶度,聚合物与LiClO4络合物的室温电导率较高,35℃时的电导率随聚氧乙烯链段分子量变化出现峰值。以电导率最高的络合物为电解质,Na1+xV3O8复合物和Li片分别为正、负极组装了薄型锂电池并测定其放电性能。

Abstract: Aseries of oxymethylene-linked polyoxyethylene multiblock polymer were synthesized by condensing dichloromethane with poly (ethylene glycol)(PEG) of different mol.wt.in the presence of potassium hydroxide powder. The multiblock polymer exhibited a certain crystallinity, and its LiClO4 complex showed a high room temperature conductivity.Alithium battery has been constructed using LiClO4 complex of the multiblock polymer as the electrolyte and Na1+x V3O8 composite as the cathode.The performance of the battery has been investigated.
