摘要

应用交流阻抗法研究Li/SOCl2、BCX电池放电过程碳、锂电极阻抗变化并测试外加电压和并联超电容对电池放电初期电压的影响.测试表明,锂电极阻抗在放电初期迅速减小了80%~90%,直到放电末期,阻抗几乎不变;碳电极阻抗至放电末期才迅速增大;BCX电池有较高开路电压可改善放电电压滞后;电池并联超级电容器可抑制放电电压滞后.

Abstract

The impedance change of both lithium and carbon electrodes during the process of discharge was studied by AC impedance spectroscopy.It shows that the impedance of lithium electrode at initial stage was reduced by 80%~90% and kept nearly unchanged after wards;the carbon electrode impedance initially did not change much but quickly increased just before the end of discharge.The improvement of voltage delay might be related with the higher open-circuit voltage of BCX cell.It is suggested that the voltage delay problem may be solved by the application of supercapacitor.
