Electroless Tin Plating Method of Hydrogen Storage Alloy Powder for Electrode

摘要

The present invention relates to a method for producing LaNi₅And MmNi₅Electrolytic tin plating is performed to increase the electrical conductivity, thermal conductivity and moldability of the hydrogen storage alloy powder of the system. LaNi₅And MmNi₅Based hydrogen storage alloy powder was subjected to ultrasonic degreasing for 2 minutes in an acetone solution to obtain SnCl₂And PdCL₂For about 2 minutes, and then 10% H₂SO₄And the electrodeposition of the hydrogen storage alloy powder for electrodes to be subjected to the chemical plating treatment so that the precipitation rate can be precipitated at a rate of 46.6 mg in a plating solution at room temperature made of a composition of 55 gr / l of thiourea and 39 gr / It is a Hezzhai plating method.
