ABSTRACT:
A manufacturing method for a hydrogen-storage-alloy powder for batteries, which is a useful material for a negative electrode of a nickel-hydrogen secondary battery whose internal pressure in an overcharged state is low, the method comprising a process for crushing a hydrogen-storage-alloy ingot into a coarse alloy powder in a non-oxidizing atmosphere, and a process for mechanically grinding the coarse alloy powder in contact with an aqueous solution in which any one of salts including a sulfite, hydrogen phosphate, and dihydrogen phosphate is dissolved or with an aqueous alkali solution containing cobalt.
