摘　　要：本文应用自制的小型Zn-MnO_2电池,研究电池化学阻抗及正、负极对电池整体阻抗的影响,实验证实了ZnMnO_2电池阻抗谱的高频半圆为锌负极所致,低频段扩散阻抗为MnO_2正极混合物所致。并通过电池放电前后电化学阻抗比较,讨论了影响电池电性能的主要因素。The influence of electrochemical impedance and positive and negative electrodes on the total impedance of battery was studied based on laboratory Zn-MnO2 cells. This experiment showed that Zn negative electrode dominated the high frequency range of electrochemical impedance spectra while the MnO2 positive electrode contributed the low frequency ran of the electrochemical impedance spectra.
