Effective thermodynamic alteration to Mg(NH2)2–LiH system: achieving near ambient-temperature hydrogen storage

Abstract

A strategy for thermodynamic improvement of 2Mg(NH2)2–3LiH composite via “stabilizing” the dehydrogenated product LiNH2 was developed. By introducing LiI, LiBr and LiBH4 to the composite, hydrogen release at 0.1 MPa equilibrium pressure is thermodynamically allowed at 333, 320 and 337 K, respectively, which are ten degree Celsius lower than the pristine composite. Moreover, the dehydrogenation kinetics and reversibility are significantly improved.
