摘　　要：含金属氢化物电极的ＭＨ－Ｎｉ电池因为无镉污染而受到人们广泛重视，能够快速充电，是广大用户对ＭＨ－Ｎｉ电池性能要求的一个重要指标，要想实现这点必须提高ＭＨ电极上的氧复合速度。ＭＨ电极上的氧复合通过两条途径进行，即化学复合与电化学复合。确定ＭＨ电极上氧复合的实质，对于指导快速充电ＭＨ－Ｎｉ电池的开发具有非常重要的意义。通过一系列实验及理论计算对ＭＨ电极上氧的化学复合速度和电化学复合速度作了较细致的描述，发现电化学复合速度明显大于化学复合速度。At present Ni MH battery with MH electrode is stressed as a promising battery,because of having no cadmium pollution .It is very important to improve the O 2 recombination rate on MH electrode for getting high charging rate.The O 2 recombination on MH electrode have two paths,i.e.,electrochemical and chemical recombination.It is very important for devoloping rapid charging Ni MH battery to define the essence of oxygen recombination on the MH electrode.In this paper,the comparison of chemical recombination of oxygen with electrochemical recombination of oxygen was discussed through experiments and calculations.It was shown that the rate of electrochemical recombination is faster than that of chemical recombination.
