ABSTRACT:
An alkaline storage battery made using a hydrogen-storing alloy for the negative electrode has suffered from the problems that the negative electrode is oxidized with oxygen gas generated from the positive electrode during overdischarge to cause increase of internal resistance and deterioration of charging and discharging cycle characteristics. Disclosed is a solution to the above problems which incorporates into the hydrogen-storing alloy negative electrode one of yttrium and yttrium compounds or a mixture thereof in such a state that it covers the surface of the hydrogen-storing alloy powder.
