| Abstract: | A new kind of cobalt monoxide powder covered with a layer of high - valence cobalt oxide was prepared by a new method and used as catalyst in nickel positive electrode for nickel-metal hydride battery. It was found that the effectiveness of nickel hydroxide has been increased to up 95%,the large current charging -discharging performance has been improved and the cycling life of the cell has been increased. The relationship between the performance of the cell and the preparation conditions,amount of the cobalt powder surface oxidation ratio of positive electrode and negative electrode has been studied. |
