Abstract

Magnesium borohydride (Mg(BH4)2) is a promising material for hydrogen storage because of its high gravimetric storage density (15.0mass%). We intended to synthesize Mg(BH4)2 by decomposition reaction of LiBH4 with MgCl2 by heat treatment without using a solvent, where the product consists of LiCl and a compound of magnesium, boron and hydrogen. Hydrogen desorption temperature of the product is approximately 100K lower than that of LiBH4 and the decomposition consists of a two-step reaction. The products of the 1st and 2nd decomposition reactions are MgH2 and Mg, respectively. This result indicates the following two-step reaction (1st reaction: Mg(BH4)2→MgH2+2B+3H2, 2nd reaction: MgH2→Mg+H2). The first decomposition peak is dominant and is around 563K. The 2nd decomposition occurs at the temperature greater than 590K.
