【摘要】 合成一种新型超支化聚醚类固体聚合物电解质。通过交流阻抗技术测试分析了电解质的离子导电性能,结果表明:温度、锂盐添加量均对离子电导率有较大影响,当锂盐添加含量为30wt%时,电导率最高(80℃时5.45×10-4 S/cm:室温1.2×10-5 S/cm)。
【Abstract】 A novel kind of polymer electrolyte based on hyperbranched polyether was prepared,and its ionic conductivity was studied by electrochemical impedance spectroscopy(EIS).The results show that the adding amount of lithium salt and testing temperature had effect on ionic conductivities of the polymer electrolytes. When the content of LiCF3SO3 is 30wt%,the electrolyte possessed the highest ionic conductivity,which is 5.45×10-4 S/cm at 80℃,and 1.2×10-5 S/cm at temperature.
