Abstract

Using a planetary ball mill and starting from a mixture of Mg₂Ni and Ni with a Mg atomic content ranging from 40 to 60 at.%, we have elaborated amorphous phase alloys with little quantities of residual Ni. The synthesis of the amorphous phase proceeded at 6.49 W g^-1 shock power, for milling durations ranging from 8 to 10 h for Mg₄₀Ni₆₀ and Mg₆₀Ni₄₀ samples, respectively. The best electrochemical capacity (470 mAh g^-1, equivalent of MgNiH_2.0) was obtained for the Mg₅₀Ni₅₀ sample synthesized in milling duration 10 times shorter than that commonly reported in the literature.
