| 摘 要： | 改变环境温度下分析了原电池的阻抗响应.基于低频扩散阻抗、高频区域半圆对应的线性极化电阻等随电池放电态的变化规律,分析了正、负极对原电池阻抗的贡献,指出了原电池放电性能改进的关键是提高正极性能.不同温度下测量的Nyquist图上,低频域的阻抗数据的斜率随放电态的变化规律不同:在280K,斜率随放电态增加而增大并接近1;在...

| Abstract: | At various environmental temperatures,the impedance spectrum of Zn-MnO2 battery were examined.Based on the changing rules for the low-frequency diffusion impedance and the linear polarization resisitance in high-frequency area varying with the battery discharging state,the contribution of positive and negative electrodes were analyzed.It was pointed out that the important for primary battery was to improve the performance of positive electrode.The dependence of slope of impedance data in low-frequency area ... |
