| 摘 要： | 采用球形Ni(OH)2作为正极添加剂,使MnO2电极在7 mol／L KOH溶液中的可充性得到显著改善.对Ni(OH)2和曾广泛研究的Bi2O2添加剂修饰的MnO2电极的循环伏安图谱进行了对比性分析,初步明确了Ni(OH)2的作用机理.模拟电池恒流充放电实验证明,Ni(OH)2添加剂在实际可充碱锰电池中作用效果明显优于Bi2O3.

| Abstract: | The rechargeabitity of electrolytic MnO2 electrodes in 7 mol/L KOH solution was studied by methods of the cyclic voltammetry and constant recharge/discharge of model cells. It was observed that the spherical Ni(OH)2 additive showed a positive effect on the reversibility of Mn2 electrodes. A comparative analysis of voltammograms of MnO2 electrodes modified by Ni (OH)2 and Bi2O3 was given to illustrate the interactions of Ni(OH)2 and manganese oxides. . |
