摘要
研究了不同荷电态下LR6型商品碱锰电池的阻抗特征。随着荷电态(SOC)的降低,电池内阻最初缓慢地增加,在29.6%～44.9%SOC时出现飞跃式增加。结果表明,目前电池检测标准使用的1 000 Hz频率不适合于低SOC的电池;线性极化电阻(Rp)增加,在21.9%SOC附近出现突跃式变化。
The impedance characteristics of LR6 type commercial alkaline Zn/MnO2 battery at different state of charge （SOC） were studied. The results showed that as the SOC decreased, the internal resistance increased slightly at first, and then increased dramatically at 29.6% - 44.9% of SOC. The frequency of 1 000 Hz which was used to test the internal resistance of battery in the test standard was not suitable for these batteries with low SOC. With the decrease of the SOC, the linear polarization resistance （R,） increased slightly and increased dramatically when the SOC was about 21.9%.
