中文摘要: 用交流阻抗法和放电试验研究了Li/SOCl₂电池放电初期的电池阻抗变化、放电最低电压、电压滞后,以及电池并联超电容放电时电池支路和超电容支路的电流变化.结果表明,放电电压滞后过程对应于放电时电池负极锂电极表面钝化膜被破坏的过程;通过建立数学模型,根据放电前锂电极阻抗可较准确地预测指定负载电阻放电时的最低电压和电压滞后;并联超级电容器能有效抑制放电电压滞后.

中文关键词: Li/SOCl₂电池交流阻抗电压滞后最低电压预测超级电容器

Abstract:The technique of AC impedance spectroscopy and the method of discharge are used to study the impedance change,the lowest voltage,the voltage delay,the hybrid cell's current change,including the Li/SOCl₂ cell branch and the supercapacitor branch during the initial discharge.As a result,the process of voltage delay is corresponded to the process that the resistance passive layer forming on the lithium metal surface is destroyed;through the model built by mathematic means,the lowest voltage and the voltage delay extent could be predicted accurately during initial polarization of the Li/SOCl₂ cell,it is suggested that the voltage delay problem be solved by means of the application of supercapacitor.
