摘要
用聚乙二醇（分子量６００）、聚丙二醇（分子量１０００）和二氯甲烷在氢氧化钾存在下合成了氧亚甲基连接的聚氧乙烯－聚氧丙烯多嵌段聚合物（（ＰＥＯ－ＰＰＯ）ｎ），研究了它与ＬｉＣｌＯ４络合物的离子导电性能，以电导率最高的络合物为电解质，Ｎａ（１＋ｘ）Ｖ３Ｏ８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。
series of oxymethylene-linked polyoxyethylene-polypropylene multiblock copolymer were synthesized by condensing dichloromethane with polyethylene glycol (PEG)and polypropylene glycol (PPG) in the presence of potassium hydroxide power. The conductivity of LiClO_4 complex of the oxymethylene-linked polyoxyethylenepolyoxypropylene multiblock copolymer was investigated. A lithium battery has been constructed using LiClO_4 complex of the multiblock copolymer as the electrolyte and Na_(1+x) V_3O_8 composite as the cathode. The performance of the battery has been investigated.
