Polymer electrolytes based on poly(ethylene oxide)-lithium triflate (PEO-LiCF3SO3) and poly(ethylene oxide)-lithium sulphate (PEO-Li2S4) were prepared by using solution casting method. Measurements of conductivity and dielectric were carried out on these films as a function of frequency at various temperatures. It was observed that PEO-LiCF3SO3 polymer electrolytes have higher conductivity. The interaction between PEO and Li salts were studied by Fourier transform infrared (FTIR).
采用溶液浇铸法制备了基于聚环氧乙烷-三氟甲磺酸锂（PEO-LiCF3SO3）和聚环氧乙烷-硫酸锂（PEO-Li2S4）的聚合物电解质。在不同温度下，对这些薄膜进行了电导率和介电常数随频率变化的测量。观察到PEO-LiCF3SO3聚合物电解质具有更高的电导率。通过傅里叶变换红外光谱（FTIR）研究了PEO与锂盐之间的相互作用。
