Electrochemical charge-discharge-cycling measurements were made on electrode samples prepared from alloy powders of composition MmNi3.55Co0.75Mn0.3Al0.4 produced by inert gas atomization with different melt superheat,solidification rate, post-solidification cooling rate and atomizing atmosphere. Effects of the above gas atomizing parameters on electrochemical properties of the electrodes, such as discharge capacity, cyclic stability and activation behavior, were studied. It is shown that the alloy powders of 30～75μm in diameter have excellent electrochemical properties when they are prepared under conditions of low melt super-heat, high atomizing gas purity and post-solidification cooling rate.
