The working principle and application of hydrogen storage alloy, the basic types of hydrogen storage alloy, development history and development trend are summarized. MmNi5 series of rare earth alloy and Laves phase alloy development and application of the more mature, but its hydrogen storage density is not high. High-capacity vanadium solid solution type alloys and magnesium-based alloys are the new trends in the development of hydrogen storage alloys. At present, it is mainly through the addition of alloying elements, the development of preparation technology to improve the microstructure and the appropriate surface treatment to improve the hydrogen absorption and desorption properties and activation properties of vanadium solid solution alloy and magnesium-based alloy at normal temperature and pressure.
