A method for producing a hydrogen absorbing alloy powder and an electrode using the hydrogen absorbing alloy powder obtained by the method

摘要

The present invention relates to a method for producing a hydrogen absorbing alloy powder which is excellent in initial activity when used in a nickel-metal hydride secondary battery and excellent in storage stability and handling property. In particular, the present invention relates to a process for treating a hydrogen absorbing alloy which has been pulverized with a solution containing a condensed phosphoric acid and / or phytic acid having 2 to 20 phosphorus atoms in one molecule, Absorbing alloy powder.
