发明名称 HYDROGEN-OCCLUDING ALLOY, POWDER OF HYDROGEN-OCCLUDING ALLOY, PROCESSES FOR PRODUCING THESE, AND NEGATIVE ELECTRODE FOR NICKEL-HYDROGEN SECONDARY BATTERY
摘要 A hydrogen-occluding alloy which is reduced in cobalt content, has a satisfactory balance among activity, corrosion resistance, and life characteristics, and has excellent suitability for recycling. The hydrogen-occluding alloy has a composition represented by the formula (1), is constituted substantially of a single phase, and has an average crystal grain diameter of 15 microm or smaller and a major axis/minor axis ratio in each crystal of 3 or higher. RNiaCobAlcMndMe (1) (R is any of rare earth elements including yttrium, etc.; M is magnesium, iron, copper, zirconium, etc.; and 3.30<a<=5.15, 0.10<=b<=0.50, 0.15<=c<0.35, 0.10<=d<=0.45, 0<=e<=0.50, 5.10<=a+b+c+d+e<=5.50, and 0.1<=c/d<=5.0.)
