ABSTRACT:
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.
