摘要： PROBLEM TO BE SOLVED: To provide a method for producing hydrogen storage alloy for easily producing the alloy, the method which intends to further enhance hydrogen storage or discharge properties of Mg, uses a ball mill which produces nanotexture and nanostructure and is simple, and from the viewpoint that the addition of a small amount of catalyst increases a hydrogen storage quantity and a hydrogen storage rate at a lower temperature, (1) uses a liquid catalyst for progressing mixing on a molecule level, and (2) selects a metal which forms no solid-solution with Mg since, when alloying with Mg is caused, a hydrogen storage quantity is reduced compared with the case where Mg is a simple substance. SOLUTION: In the production method, titanium halide as tetravalent titanium mainly made up of magnesium metal and containing metal titanium in an amount of at least 1wt.% to the magnesium is mixed with a cyclohexane solvent by a ball mill, the mixture is dried, and thereafter, the obtained composition is subjected to hydrogen-dehydrogenation treatment for at least one time, so that the specific surface area of the alloy composition is increased.
