【摘要】 用交流阻抗法研究了 (PEO1 ) 1 0 LiClO4 Al2 O3和 (PEO2 ) 1 6 LiClO4 碳酸乙烯酯 (EC)两种复合聚合物电解质体系的电导率 ,给出了等效电路和各拟合元件的物理意义。当阻抗谱图发生严重变形时 ,提出一种比较简单的计算聚合物电解质电导率的方法———阻抗虚部最大值法更多还原

【Abstract】 Polymeric electrolytes of (PEO 1) 10 LiClO 4 Al 2O 3 (PEO:poly(ethyleneoxide)) and (PEO 2) 16 LiClO 4 EC (EC: ethylene carbonate) were prepared. We proposed an equivalent circuit and gave the meaning of the concerned circuit elements. When the impedance spectrum deformed severely, the ionic conductivity of polymer electrolyte was determined by using the maximum of imaginary impedance, which is a convenient method.更多还原
