Patent ID: 8105974

Claim:
A process of forming a hydrogen storage material comprising the steps of: providing a first material of the formula: M(BH 4 ) x where M is an alkali metal or an alkaline earth metal and 1≦x≦2; providing a second material selected from: M(AlH 4 ) x where 1≦x≦2, a mixture of M(AlH 4 ) x 1≦x≦2 and MCl x where 1≦x≦4, a mixture of MCl x where 1≦x≦4 and Al, a mixture of MCl x where 1≦x≦4 and AlH 3 , a mixture of MH x where 1≦x≦2 and Al or AlH 3 , Al, and AlH 3 ; combining the first and second materials at an elevated temperature and at an elevated hydrogen pressure for a time period forming a third material having a lower hydrogen release temperature than the first material wherein the third material includes a partially substituted borohydride metal cation with another metal cation, or partially substituted borohydride boron with a metal, or a partially substituted cation and boron in the borohydride.
