| 摘 要： | 良好结晶性的氢氧化镍电极材料并不具有电化学活性,电极活化要吸收一些水分,但水的精确性质和位置并不清楚.本文借助FTIR和TG-DTA在进一步确定活性材料中含有自由水和结合水的基础上,考虑到水分子的存在与镍电极氧化还原反应密切相关,进而提出水分子是电极/电解液界面质子运动载体的设想,并得到相应的电极反应机理.

| Abstract: | The inactive nickel hydroxide materials in fine crystalline state can be electrochemi-cally activated when it absorbs some water from the electrolyte, but it is unknow for the position and function of water in the nickel hydroxide crystal lattice. This paper focuses on deciding the existence of free and combining water in the active material through the FTIR and TG-DTA analysis. With considering the existence of water molecule to be closely related to the oxidation and reduction reaction of nickel hydroxide electrode, it is assumed that water is a carrier of the proton diffusion and transfer, and then the reduction-oxidation reaction mechanism is obtained by the hypothesis. |
