Abstract
The relation between the discharge capacity and cycling number of mech anically alloyed MgxNi100-x amorphous electrode alloys was proposed on the basis of the fact that the degradation of discharge capacity was mainly caused by the oxidation of magnesium and nickel. The experiment al data fitted the deduced equation well. Partial substitution of Co, Si or Al for Ni may improve the cycling life of amorphous MgxNi100-x a lloys just as predicted by the deduced equation; however, their initia l discharge capacities were dramatically reduced.
