Abstract

Amorphous and crystalline hydrogen storage alloys of the composition NdMgNi 4 - x Co x (x = 0.0, 0.2, 0.4, 0.6, 0.8, 1.0) were prepared by mechanical alloying and their electrode properties were investigated systematically by a simulated battery test. It was found that the maximum discharge capacity of the amorphous alloys was much higher than that of the crystalline ones, and the cycle life of the negative electrode changed with x from 0.0 to 1.0, and especially when x = 0.4, the alloy with the amorphous phase had the best cycle stability.
