摘要
通过循环伏安法、计时电位法研究了纳米碳管的添加量对MmNi5合金在碱性溶液中电化学储氢性能的影响。结果表明,添加纳米碳管可以明显改善MmNi5合金电化学储氢性能;当纳米碳管与MmNi5合金的质量比为1∶16.7时,电极的电化学活性最好,电化学储氢量提高达到62.41%。
The electrochemical hydrogen storage performance of MmNi5-type electrodes doped with carbon nanotubes(CNTs) in an alkaline solution was investigated with cyclic voltammetry(CV) and chronopotentiometry(CP). The results showed that the electrochemical hydrogen storage performance of MmNi5-type electrodes doped with CNTs was notably improved. Furthermore, electrochemical activation ability of the electrode with the CNTs and MmNi5 weight ratio of 1 : 16.7 was the most excellent, and the discharging capacity increased to 62.41%.
