PURPOSE:To improve the hydrogen adsorption rate by crushing an ingot of hydrogen storage alloy in an aq. soln. of a metal salt to coat the alloy surface with the metal element of the salt. CONSTITUTION:The ingot of a hydrogen storage alloy is pulverized by a ball mill, stamping mill, etc., in an aq. soln. of at least one kind of metal salt selected from palladium, nickel, cobalt, titanium, manganese and aluminum salts. The concn. of the metal slat in the soln. is preferably controlled to <=0.001wt.%, expressed in terms of the metal. The wt.% is derived from (coating metal/hydrogen storage alloy+coating metal in amts.)X100. Besides, the crushing (dipping) time in the soln. is controlled to about 5-6min, and the objectives are sufficiently achieved even when the soln. is kept at ordinary temps. |
