摘要： PURPOSE:To produce a hydrogen-absorbing electrode which is chemically stable to a liquid electrolyte and from which hydrogen-absorbing alloy particles are not separated even after repeated absorption and release of hydrogen by coating the alloy particles with metallic nickel and fixing the coated particles to a conductive supporter. CONSTITUTION:Hydrogen-absorbing microcapsules prepared by coating particles of a hydrogen-absorbing alloy with metallic nickel have the same hydrogen- absorbing and releasing ability as the alloy, can be easily made to absorb hydrogen and can be easily compressed and molded. The alloy particles firmly adhere to each other through nickel in a molded body prepared by subjecting thus prepared hydrogen-absorbing microcapsules to compression molding. Therefore, even after charge and discharge are repeated, the alloy particles are not pulverized and they are not separated from the electrode. Accordingly, a hydrogen- absorbing electrode satisfying all necessary requisites can be produced by selecting a proper alloy according to the condition of battery operation and coating particles of the alloy with metallic nickel by nonelectrolytic autocatalysis plating before pressing and fixing the particles to a conductive supporter.
摘要翻译：目的：制备对液体电解质化学稳定的吸氢电极，即使在通过用金属镍涂覆合金颗粒并将涂覆的颗粒固定到导电支持者。构成：通过用金属镍涂覆吸氢合金颗粒制备的吸氢微胶囊具有与合金相同的吸氢和释放能力，可以容易地吸收氢气并且可以容易地被压缩和模制。合金颗粒通过将由此制备的吸氢微胶囊进行压缩成型制备的成型体中的镍彼此牢固地粘合。因此，即使在重复充放电之后，合金粒子也不会被粉碎，并且不与电极分离。因此，通过根据电池操作的条件选择适当的合金，并且通过非电解自催化电镀将合金涂覆在金属镍上的颗粒，然后将颗粒压固并固定到导电支撑体上，可以制备满足所有必要条件的吸氢电极。

摘要： A cell provided with a gaseous diffusion electrode is constituted of the gaseous diffusion electrode, a hydrogen-absorbing alloy electrode, and a chargeable auxiliary electrode wherein nickel hydroxide is used as the active material thereof. The chargeable auxiliary electrode may be disposed either between the gaseous diffusion electrode and the hydrogen-absorbing alloy electrode, or on the opposite side of the gaseous diffusion electrode to the hydrogen-absorbing alloy electrode. The chargeable auxiliary electrode that can be used may be either a sintered-type nickel electrode for securing a long life span, or a foamed-type nickel electrode or a fiber-type nickel electrode for securing a high capacity. The hydrogen-absorbing alloy electrode has a layer of at least one of metallic nickel, cobalt and copper on the surface of the alloy in order to suppress oxidation thereof at the time of over discharge.
