Abstract
(EN)
Provided are a hydrogen storage alloy suitable for a negative electrode of an on-board alkaline storage battery, an alkaline storage battery using the same, and a vehicle. Provided are: a fine-grained hydrogen-storage alloy that is used in an alkaline storage battery, the hydrogen storage alloy having, as a main phase, a crystalline structure of an A2B7 type structure, and being expressed by the general formula (La1-aSma)1-bMgbNicAldCre (wherein, the subscripts a, b, c, d, and e satisfy the conditions of 0≤a≤0.35, 0.15≤b≤0.30, 0.02≤d≤0.10, 0≤e≤0.10, 3.20≤c+d+e≤3.50, and 0<a+e); and an alkaline storage battery that uses said hydrogen storage alloy in a negative electrode. A vehicle having said alkaline storage battery as an electric power supply source for a motor is also provided.
