锌锰电池贮存前后的交流阻抗行为

The AC Impedence Behaviour of Undischarged Commercial Leclanche Cells Before and After Storage

本文应用交流阻抗技术研究了R20型Zn-MnO_2干电池在贮存前后的交流阻抗行为,建立了等效电路。对阻抗图谱的差别进行了分析和讨论,得出了一些对电池进行无损检测的结论。

The AC impedence behaviour of undischarged commercial Leclanche cells (R20 type)before and after storage for half a year were studied. Equivalent circuits were established. The differences remained in the cells before and after storage were discussed. Conclusions was this method could be used as nondestructive test of leclanche cells.
