[0001] The invention relates to the technical field of hydrogen storage materials, and in particular to a high hydrogen storage composite material and a preparation method thereof. Background Art

[0002] As a clean, environmentally friendly, efficient and sustainable new energy, hydrogen energy has the characteristics of abundant sources, convenient and efficient conversion with electricity, diverse storage and transportation methods, and good environmental compatibility. It has a wide range of applications in the fields of power energy, transportation, chemical industry, electronics industry, metallurgy, light industry, etc. It is regarded as the clean energy with the greatest development potential in the 21st century. Hydrogen energy applications include hydrogen preparation, storage, transportation and application, among which hydrogen energy storage is the key and difficulty. The development of safe and efficient hydrogen storage technology is a prerequisite for large-scale application of hydrogen energy.

[0003] Existing gas storage materials mainly include metal composite materials and organic liquid materials. Certain transition metals, alloys and intermetallic compounds, due to their special crystal structure, allow hydrogen atoms to easily enter their lattice gaps and form metal hydrides, so the hydrogen storage capacity is large. However, there are many types of metal alloys, and the hydrogen storage capacity of each metal is different. Storing hydrogen at different temperatures requires the use of different types of alloys, which is very troublesome.

[0004] In view of the above problems, a high hydrogen storage composite material and a preparation method thereof are proposed. Summary of the invention
