Abstract

This invention provides the continuously cyclic pulverization process for fabricating hydrogen storage alloys used in negative electrodes of nickel metal hydride batteries. The conventional mechanically roughly shattering or finely grinding is not used in this process and only hydride-dehydride pulverization method is used. The hydride-dehydride pulverization method is designed as the type of continuously cyclic hydride-dehydride pulverization, in which hydrogen absorbed by the pulverized hydrogen storage alloys is heated and is released. Another set of hydrogen storage alloys is used as the hydrogen absorption source so as to have the cyclic effects of hydride and dehydride. In this manner, the cyclic utilization of hydrogen can be effective and the hydrogen storage alloys are continuously pulverized. Under appropriate control of hydrogen absorption temperature, pressure and time, the hydrogen storage alloys are directly pulverized into powder, which is required for fabricating negative electrodes of nickel metal hydride batteries, after one time of hydrogen absorption process. The particle-size distribution of powder is concentrated and the ratio occupied by powder having size smaller than 100 mu m is more than 90%. Therefore, the multi benefits, such as decreasing production cost and enhancement of environment protection, can be obtained.
