Abstract

The hydrogen storage material Mg-Ni-MnO₂ was prepared by mechanical alloying under the hydrogen atmosphere and its phase transformation rate in hydrogen absorption was studied using the self-designed measurement apparatus. The experimental results show that the phase transformation rate has a maximum value in the hydrogen absorption; and the milling time has great effect on the time of maximum value appearance and maximum value of phase transformation rate. At the early stage, the rate is controlled by particle surface effect, and at the smooth stage, the mechanism of phase transformation is influenced by the particle size.
