Abstract
AbstractIonomeric networks (IN) with lithium sulfate and salt‐solvating oligo(oxyethylene) chain were synthesized on the purpose of improving the conductivity of single‐Li+−ionic conductors. Li+−ionic conductivity 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 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 Arrhenius plots, suggesting that the ionic conduction is primarily influenced by segmental motion of the polymer host. In addition, WLF (Williams‐Landel‐Ferry) equation is used to analyze the conductivity data, from which the related WLF parameters are determined.
