Ionomeric networks(IN)with lithium sulfate and sait-solvating oligo(oxyethylene)chainwere synthesized on the purpose of improving the conductivity of single-Li~+-ionic conductors.Li~+-ionicconductivity depends considerably on the salt content of the INs although the apparent degree of cross-linking is fixed in a constant of 10 mol%.As salt content(Li/O value)equals 0.0467,conductivity ofthe IN containing neither small-molecular salt nor low molecular weight plasticizer reaches a maximumof 7×10~(-6) S/cm at 25℃.Temperature-conductivity relationship of the INs shows curved Arrheninsplots,suggesting that the ionic conduction is primarily influenced by segmental motion of the polymerhost.In addition,WLF(Williams-Landel-Ferry)equation is used to analyze the conductivity data,from which the related WLF parameters are determined.

Li ~ + -ionicconductivity depends considerably on the salt content of the INs the apparent degree of cross-linking is fixed in a constant of 10 mol% .As salt content (Li / O value) equals 0.0467, the conductivity of the IN containing neither small-molecular salt nor low molecular weight plasticizer reaches a maximum of 7 × 10 ~ (-6) S / cm at 25 ° C.Temperature-conductivity relationship of the INs shows curved Arrheninsplots, suggesting that the ionic conduction is primarily influenced by segmental motion of the polymerhost.In addition, the WLF (Williams-Landel-Ferry) equation is used to analyze the conductivity data, from which the related WLF parameters are determined.
