文摘

A novel LiAlBH composite is prepared by ball milling LiBH4 and AlH3. LiBH4AlH3 shows better hydrogen desorption property than LiBH4Al. Reaction mechanism between LiBH4 and AlH3 is revealed. Desorption products of 2LiBH4AlH3 are AlB2 and LiAlB compounds. Product yield depends on the free surface area of Al particle.
