The effects of rapid quenching on the cycle stability of the H2-storage electrode alloy with AB2 Laves phase were investigated comprehensively. The phase structures and morphologies of as-cast and quenched alloys were determined and observed by XRD and SEM. The results showed that the influences of rapid quenching on the cycle stability of the H2-storage electrode alloy with AB2 Laves phase was closely related to the compositions of the alloys. The cycle life of Ti-based electrode alloy could be enhanced in certain degree by rapid quenching. For Ti-Zr-based electrode alloy, its cycle life could be exalted dramatically with the increase of quenching rate. The main reason of different influence of rapidly quenching on the cycle stability of the electrode alloy was attributed to that the quantities of the amorphous formed by rapid quenching in alloys were different.
