Abstract
A hydrogen storage alloy suitable for a negative electrode of an on-board alkaline storage battery, an alkaline storage battery using this hydrogen storage alloy, and a vehicle; wherein a fine-grained hydrogen storage alloy is used for an alkaline storage battery that has a crystal structure of an AB-type structure as a main phase and is represented by a general formula: (LaSm)MgNiAlCr(where suffixes a, b, c, d, and e meet the following conditions: 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 using this hydrogen storage alloy for a negative electrode. A vehicle also includes this alkaline storage battery as an electricity supply source for a motor.
