Patent ID: 8440100

Claim:
A method of generating a hydrogen storage composition, comprising the steps of: creating a quaternary LiBNH composition mixture or composition premix, wherein the quaternary LiBNH composition mixture is created by ball milling LiBH 4 and LiNH 2 to form a quaternary LiBNH composition; adding a MgH 2 to the quaternary LiBNH composition to form the quaternary LiBNH composition mixture; wherein the composition premix is created by mixing LiBH 4 , LiNH 2 , and MgH 2 together to form a composition premix; placing the quaternary LiBNH composition mixture or composition premix into a high energy ball mill; purging the ambient air from the ball mill using a argon/hydrogen gas, wherein the argon/hydrogen gas is 95% argon and 5% hydrogen; ball milling the quaternary LiBNH composition mixture or composition premix for 5 hours with argon/hydrogen gas purging to form nanoparticles consisting essentially of MgH 2 and quaternary LiBNH wherein the nanoparticles fill the voids in the quaternary structure.
