Ti-based hydrogen storage alloys have attracted much attention because of their good hydrogen storage performance, low cost and simple design for hydrogen storage system. However, its shortcomings are relatively high platform pressure, not easy to be activated, slow heat transfer speed, easy to be poisoned by impurity gases, etc. In order to improve the thermodynamic stability and hydrogen storage capacity of alloy hydrides, research progress of Ti-Fe, Ti-Cr, Ti-Mn, Ti-Zr, Ti-V, Ti-Ni based titanium hydrogen storage alloys is reviewed in this paper, focusing on the effects of element replacement or addition, manufacturing process and heat treatment on the hydrogen storage properties of titanium-based alloys. Methods and measures to improve the activation performance of titanium-based hydrogen storage alloys are also presented. At last future developments of titanium-based hydrogen storage alloys are prospected.
