摘要
通过制备纳米级的 β-Ni(OH) 2 粉体然后按一定比例掺杂 Al(OH) 3和 Ni粉制成复合电极 ,研究其电化学性能 .实验结果表明 ,其电极结构稳定 ,活性增强 .开路电位达 2 .5 V,放电电位平稳 ,放电容量明显增大 .电极经 3 .0× 1 0 - 3A/cm2 恒电流充电 5 h后以 0 .7× 1 0 - 3A/cm2 恒电流放电可达到 1 6h.
The nano sized β Ni(OH) 2 powder was synthesized and mixed with different amount of Al(OH) 3 and Ni powders to fabricate electrodes. The electrodes propared exhibit increased activity, stable discharging potential, increased capacity with open circuit potential up to 2 5 V. The electrode after 5 hours charging under constant current of 3 0×10 -3 A/cm 2 could be discharged at 0 7× 10 -3 A/cm 2 for period of 16 hours.
