Lithium alanate or LiAlH 4 has been used as a destabilizing agent in MgH 2 –LiAlH 4 (Mg–Li–Al) due to its high capacity of hydrogen, which is 10.5 wt.%, and low onset desorption temperature (∼150°C). In
Metal hydrides - chemisorption. The storage of hydrogen in a metal hydride involves the formation of a M-H bond, where M is the metal. In the simplest case the general reaction scheme is: M + x H 2 → 2 x H + M. M + 2 x H → MH 2x. The hydrogen comes into contact with the storage material (M).
