氧化银电极中镀银泡沫镍的性能研究

Study on the properties of silver-plated foam in silver oxide electrode

本文通过恒电阻放电测试方法,对铝氧化银电池中采用镀银泡沫镍为集流体的激活初期倍率性能进行研究。实验结果表明镀银泡沫镍为基体的氧化银电极在放电过程中电化学极化较银网为基体的氧化银电极较低,利用率较高。镀银泡沫镍为基体的氧化银电极在620m A/cm^2的电流密度下,放电截止电压为1.4V时的平均电压为1.65V,比银网为基体的氧化银电极的平均电压高70m V,利用率高近5%。

In this paper,a constant resistance discharge method is adopted to research the rate performance of silver-coated nickel foam in aluminum-silver oxide battery activated early. The results show that the electrochemical polarization of silver-plated nickel-deposited is lower than that of silver oxide electrode in the discharge process and the utilization ratio is higher than that of silver oxide electrode. The average voltage of the silver-coated nickel foam electrode is 1. 65 V that is 70 m V higher than that of silver oxide electrode and the utilization rate of the silver-coated nickel foam electrode is nearly5% higher than that of silver oxide electrode when the discharge current density is 620 m A/cm^2 and the discharge cut-off voltage is 1. 4 V.
