Abstract:

Ti-V-based hydrogen storage alloys perform well at ambient conditions and show better hydrogen storage capacity than conventional alloys. Thus, it is early utilized in purification and recovery of hydrogen, transport and storage of hydrogen and heat pump. Besides, it is also widely researched and concerned in gas mixture separation, disposure of hydrogen isotope in nuclear reactor, anode material of Ni-H and fuel cell battery. Based on the current research and development situation of Ti-V based alloys, the privileges, main constraints with the cause included and the methods of modification were briefly summarized. Moreover, to further understand the hydrogen storage mechanism of Ti-V based alloys and to build the relationship between alloy constituents and hydrogen storage properties, this review will focus on the phases and structures of Ti-V based alloys and its hydrides, optimization design of constituents and composition, as well as the development direction of it.

Key words: Ti-V based alloys, hydrogen storage, phases and structure, optimization design
