Poly(oxytetramethylene) ionene with dimethylammonium groups (DPI) was prepared, whose molecular weight between the ionic sites was 3200. When (CF_3SO_2)_2NLi was doped into DPI. at the concentration of [Li]/[-O-]=0.1, the highest ionic conductivity was observed, and it was 8.5×10^<-6> S/cm at 30℃ and 9.7×10^<-5> S/cm at 80℃. The transference number of lithium cation of this sample was measured to be ca. 0.5, which was higher than that of poly(oxyethylene)/(CF_3SO_2)_2NLi solid electrolytes. Next, silica particles with lithium ionic sites were prepared and were doped into DPI and branched poly(oxyethylene). The ionic conductivity and lithium transference number were observed to become a little lower by addition of ionic silica, however the mechanical properties was much improved. The ionic conductivity of solid electrolytes composed of lithium haloboracite and polyethylene glycol was studied, and the ionic conductive inorganic material was found to be useful for preparation of good solid state electrolyte by combination with polymers. The effect of molecular orientation of oxyethylene segments and the effect of poly(oxyethylene) content on the ionic conductivity were also investigated for high molecular branched poly (oxyethylene) and hydrin rubber, respectively, in this project.

制备了带有二甲基铵基（DPI）的聚（氧甲基乙基）离子，其离子位点之间的分子量为3200。在[li]/[ - o-] = 0.1的浓度下，观察到最高的离子电导率，在30℃时为8.5×10^<-6> s/cm，在80℃时为9.7×10^<-5> s/cm。该样品的锂阳离子的转移数量为CA。 0.5，高于聚（氧乙烯）/（CF_3SO_2）_2NLI固体电解质的0.5。接下来，制备了带有锂离子位点的二氧化硅颗粒，并将其掺杂到DPI和分支聚（氧乙烯）中。通过添加离子二氧化硅，观察到离子电导率和锂转移数量稍低一些，但是机械性能得到了很大改善。研究了由卤代石和聚乙烯乙二醇组成的固体电解质的离子电导率，并发现离子导电性无机材料可用于通过与聚合物结合组合制备良好的固态电解质。还研究了该项目的高分子分支聚集聚（氧乙烯）和水林橡胶，还研究了氧乙烯片段的分子方向以及聚（氧乙烯）含量对离子电导率的影响。
