Solid polymer electrolytes (SPEs) are prepared through thiol-ene polymerization with functionalized, potentially bio-based, aromatic monomers. Differing functionality and aromatic content of the monomers vary the glass transition temperatures (T_gs) and crosslink densities of the resulting polymers, allowing for analysis of the structure-property relationships. Though the SPEs contain repeating PEO segments, the formation of crystalline regions is avoided through the crosslinked nature of the networks. The solid polymer electrolytes exhibit high conductivity values at room temperature, the highest reaching 7.65 × 10⁻⁴ S cm⁻¹ for the DAVA-containing SPE with 50 mol% LiPF₆, and moderate lithium ion transference numbers, the highest reaching 0.39 for the DAGd-containing SPE with 25 mol% LiPF₆. Lower polymer T_g is associated with higher overall conductivity, but, the SPEs with higher crosslink densities display higher cationic transport, though the T_gs are higher. Therefore, it is determined that there exists an optimal range of polymer T_gs, crosslink densities and neat polymer dielectric constants for high cationic transport through the SPEs; extremes of these parameters are not necessarily beneficial. The promising conductivity and ion transference results, in addition to high initial decomposition temperatures in N₂ (>300 °C) and great electrochemical stability, reveal potential for these crosslinked, aromatic, thiol-ene polymers in electrolyte applications in lithium-ion batteries.

固态聚合物电解质（SPE）是通过硫醇-烯与功能化的，可能基于生物的芳香族单体聚合而成的。单体的不同官能度和芳族含量会改变所得聚合物的玻璃化转变温度（T _g s）和交联密度，从而可以分析其结构性质之间的关系。尽管SPE包含重复的PEO片段，但通过网络的交联性质可以避免形成结晶区域。该固体聚合物电解质在室温下表现出高的电导率值，最高达到7.65×10 ^{- 4} 小号厘米^{- 1}为含DAVA-SPE与50摩尔％的LiPF ₆和适中的锂离子迁移数，对于含25 mol％LiPF ₆的含DAGd的SPE，最高达到0.39 。较低的聚合物T _g与较高的总电导率有关，但是具有较高的交联密度的SPE显示较高的阳离子传输，尽管T _g较高。因此，确定存在对于通过SPE的高阳离子传输而言存在最佳的聚合物T _g s，交联密度和纯净的聚合物介电常数的范围。这些参数的极端值不一定是有益的。除了在N _2中较高的初始分解温度外，还可以实现有希望的电导率和离子转移 （> 300°C）和出色的电化学稳定性，揭示了这些交联的芳族硫醇烯聚合物在锂离子电池电解质应用中的潜力。
