Document Type and Number:
Japanese Patent JP3579273
Kind Code:
B2
Abstract:
A hydrogen absorbing alloy electrode is provided which has an excellent oxygen gas absorbing capacity and further improved in charge-discharge cycle characteristics and high-rate discharge characteristics. The electrode contains a powder prepared by mixing a hydrogen absorbing alloy powder with a powder of at least one complex oxide selected from the group consisting of a ZrO2-Y2O3 solid solution, ZrO2-CaO solid solution, CeO2-Gd2O3 solid solution, CeO2-La2O3 solid solution, ThO2-Y2O3 solid solution, Bi2O3-Y2O3 solid solution, Bi2O3-Gd2O3 solid solution, Bi2O3-Nb2O3 solid solution and Bi2O3-WO3 solid solution. Preferably the electrode contains 0.1 to 10 wt. % of the complex oxide powder based on the combined amount of the two powders.
