摘要： 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.

摘要： A method for producing a hydrogen storage alloy electrode comprising the step of treating a hydrogen storage alloy by immersing it in an alkaline solution containing cobalt ion or copper ion at a high temperature at a stage wherein the alloy is in powder state before formed into an electrode and/or at a stage wherein the alloy has been formed into an electrode. By this treatment, a hydrogen storage alloy electrode having an excellent high-rate discharge performance at a low temperature is obtained.
