摘要：

Negative electrodes consisting of a multicomponent alloy (MmNi3.6Mn0.4Al0.3Co0.7) in a porous nickel substrate were modified by using different kinds of electroless plating baths or alkaline solutions containing hypophosphite as a reducing agent. Electrochemical properties of the negative electrodes such as discharge capacity, electrocatalytic activity for the hydrogen electrode reaction (HER), and high-rate dischargeability were examined in a 6 M KOH solution. It was found that such simple surface modifications as described above improved the performance of negative electrodes.
