同时，发现稀土元素物质La掺杂可以明显改善电极反应的充放电循环可逆性，并有效抑制镍电极上的析氧反应和降低电极反应的电化学极化和欧姆阻抗，提高其放电电压。

Furthermore , the cyclic reversibility of the electrode reaction improves after doping La and the rare earth La has good effect in inhibiting the oxygen evolution reaction of sample electrode , reducing the electrode reaction of the electrochemical polarization and ohmic resistance , and increasing the discharge voltage .

当外加电位高于0.40V以后，电极表面同时发生电化学析氧反应。

When the applied potential was higher than 0 4 V , the oxygen evolution reaction occurred simultaneously .

交流阻抗实验表明，在两种电极上的析氧反应均受电荷传递控制，且相同电位下，纯铅上的析氧反应电阻略大于铅铋合金电极上的反应电阻。

It was found that the oxygen evolution reactions on both lead and lead-bismuth alloys were controlled by charge transfer step .

并且Pb-Sb电极在两种溶液中的析氢析氧反应受到比较明显的抑制作用，对铅酸蓄电池的免维护性能起到了积极作用。

And the hydrogen and oxygen evolution reaction on the Pb-Sb electrode are inhibited more obviously , which plays a positive role in the maintenance-free performance of the lead acid battery . 3 .

结果表明：阳极具有优良的耐析氯、氧反应能力；

Results showed that anode exhibited enough ability to tolerate the chlorine evolution and the oxygen evolution .

单扫伏安曲线表明氨氮在3种电极材料上的电催化反应很小，基本上是析氧、析氯反应。

The voltammetry curves showed that the electro-catalytic of ammonia on these three type electrodes was small and the main reactions were oxygen evolution and chlorine evolution .

说明在一定范围内温度的提高并未改变析氧的速控步骤，同时该过程的动力学数据还表明电极析氧反应的可逆性没有显著变化。

The thermodynamic parameters determined that the speed-control step was same , and the reversibility of oxygen evolution reaction did not change .
