| 摘 要： | 采用电化学阻抗谱法,对阻抗谱中的聚合物电解质本体电阻（Rb）与膜厚（L）的关系和固体聚合物电解质/惰性电极间的界面阻抗随直流电压的变化趋势进行了研究.结果表明,阻抗谱中聚合物电解质本体电阻（Rb）含有一定的阻塞电极/聚合物电解质间的界面阻抗;由于界面双电层电容的变化,在直流电压0.15～3 V范围内,界面阻抗随电压的增大而减小.

| Abstract: | The relationship between bulk resistance(Rb) of solid polymer electrolyte(SPE) in the Nyquist plots and the thickness(L) of SPE was investigated by using electrochemical impedance spectroscopy.It was found that Rb obtained from the impedance spectroscopy maybe contain some interface impedance.The influence of voltage on impedance of blocking electrode/SPE interface was also studied by using electrochemical impedance spectroscopy.Impedance of blocking electrode/SPE interface decreased with the increase of voltage from 0.15 V to 3 V.This phenomenon can be explained by changing the interfacial capacitance of blocking electrode/SPE interface. |
