    摘要： Methods for making hydrogen storage tanks may include disposing a substantially solid block of hydrogen-absorbing alloy within an activation vessel. Hydrogen gas may then be introduced into the activation vessel under conditions that will cause the hydrogen-absorbing alloy to absorb hydrogen and crack or break apart. Preferably, a substantially powdered hydrogen-absorbing alloy is formed thereby. Thereafter, the substantially powdered hydrogen-absorbing alloy can be transferred from the activation vessel to a hydrogen storage tank without substantially exposing the powered hydrogen-absorbing alloy to oxygen. The hydrogen-absorbing alloy is preferably ingot-shaped when introduced into the activation vessel. Further, the substantially powdered hydrogen-absorbing alloy is preferably produced by continuously breaking the ingot-shaped hydrogen-absorbing alloy within the activation vessel due to volume expansion caused by the hydrogen-absorbing alloy having absorbed hydrogen. The hydrogen gas preferably contacts the hydrogen-absorbing alloy under relatively high-pressure and low temperature conditions.

    摘要： An electrode for a sealed nickel/metal hydride battery and a method of manufacturing the same, which is capable of suppressing a decrease in the charging reserve of a hydrogen-storage alloy electrode (negative electrode) and an increase in the internal pressure of the battery, is provided. The hydrogen-storage alloy electrode is formed using a tackifier or a binder which is prepared from an organic polymer material containing the ether linkage (--O--), for example, polyethylene oxide, polypropylene oxide , or polybutylene oxide. The specified material is suitably hydrophilic, and it exhibits an oxidation resistance which is much higher than that of a conventional material containing the hydroxyl group (--OH). Therefore, the specified material is especially resistant to oxidation and decomposition at the positive electrode of the battery and can significantly reduce the production of hydrogen attributed to the oxidation and decomposition.
