摘要
研究了Ce元素作为添加剂 ,通过外掺和共沉积的方式加到Ni(OH ) 2 时对镍电极性能的影响 ,并用循环伏安法对结果进行分析。结果表明外掺法极大地提高了电极的性能 ,而共沉积加入Ce元素却不能有效地改善电极的性能 ,循环伏安实验结果表明 ,外掺法加入Ce元素时能够很好地改善电极的可逆性 ,改善了电极反应中电子的传输能力 。
Effect of cerium element which was mixed with Ni(OH) 2 by incorporation and co precipitated as additive on properties of nickel electrode were studied. The experimental results were analyzed by means of cyclic voltammetry. The results show that nickel electrodes with incorporated directly display excellent charge discharge behaviour. by contrast nickel electrodes co precipitated with cerium can not effectively improved the properties. The results of cyclic voltammetry shows that the reversibility of nickel electrode with cerium incorporated is improved as well as the transportation ability of H +, thus the properties is better.
