| 摘 要： | 通过在镍氢电池NKOH）2正极中复合添加稀土氧化物Lu2O3和Er2O3，研究了稀土氧化物的复合添加对Ni（OH）2正极高温性能的影响。充放电循环实验表明复合添加不同含量的Lu2O3和Er2O3都能够不同程度地提高正极高温充电效率。在55，60，65℃下，添加2．5％Lu2O3＋1．5％Er2O3的正极充电效率最高。循环伏安测试表明，复合添加2．5％Lu2O3＋1．5％Er2O3能够较为明显的提高Ni（OH）2正极在高温环境下的析氧副反应电位，进而提高了电极在高温环境下的充电效率。

| Abstract: | The effect of Lu2O3 and Er2O3 on the performance of nickel hydroxide positive electrode at the high temperature was studied. The experimental results show that Lu2O3 and Er2O3 as additives of the nickel hydroxide positive electrode can obviously increase the oxygen-evolution potential on the nickel hydroxide electrode and the charge efficiency at high temperature, consequently. An optimum proportion of the additives Lu2O3 and ErzOs in the active material of nickel hydroxide was given. |
