  • METHOD FOR PRODUCING METAL HYDRIDE
    Publication number: 20100135898
    Abstract: Disclosed is a method for producing a metal hydride, which enables to obtain a metal hydride from a metal imide or a metal amide. Specifically, in an air current containing a hydrogen gas having a hydrogen partial pressure of 0.1 MPa or greater, hydrogen is reacted with one or both of a metal imide and a metal amide, thereby producing a metal hydride. The metal constituting the metal amide and the metal imide is preferably lithium, sodium or potassium.

  • Hydrogen storage matter and manufacturing method and apparatus for the same
    Patent number: 7537748
    Abstract: A hydrogen storage matter contains at least a nano-structured and organized lithium imide compound precursor complex. In the hydrogen stroge matter, the lithium imide compound precursor complex has been nano-structured and organized by mixing fine powder lithium amide with fine powder lithium hydride at a predetermined ratio to prepare a mixture as a starting material, and then processing the mixture by a predetermined complex formation processing method.
