粉体Ag_2O（Ni）电极循环伏安研究

The Cyclicvoltametry Study for the Power Ag 2O(Ni) Electrode

本文用循环伏安法对粉体Ａｇ２Ｏ电极和含Ｎｉ的Ａｇ２Ｏ电极在ＫＯＨ溶液中的电化学行为进行了研究．结果表明：含Ｎｉ的Ａｇ２Ｏ电极和单纯Ａｇ２Ｏ电极在碱性溶液中的氧化还原情况有很大不同，Ｎｉ的存在使Ａｇ２Ｏ粉体电极在阴极扫描时产生的峰比单纯Ａｇ２Ｏ时强得多，说明此电极材料在电池中的放电性能优于Ａｇ２Ｏ．

The cyclicvoltametry methods are used to study for the powder Ag 2O elctrode and Ag 2O (Ni) electrode in KOH aqueous solutions.The results show that there are difference of the electrochemical behaviors between these electrodes (Ni).Because of the exist of Ni,cathodic peak of Ag 2O(Ni) electrod is larger than Ag 2O electrode and the affect is not reversible.
