摘要

In order to improve the electrochemical properties of Ti-based hydrogen storage alloys, the phase structures of Ti_0.3Zr_0.225V_0.25 Mn_0.3-xNi_0.45+x (x = 0~0.25) hydrogen storage alloys were analyzed by XRD, SEM and EDS. The electrochemical properties of alloys were investigated. The results show that these alloys are composed of C14 Laves phase matrix with hexagonal structure and C15 Laves second phase with cubic structure. With the increase of x, the activation properties of alloys are decreased, while the cycle stabilities are improved. When x = 0.05, the maximum discharge capacity of the alloy reaches to 426 mAh/g. These alloys show a great potential as negative electrode materials.
