Hydrogen Storage of Li2NH Prepared by Reacting Li with NH3

In this paper, Li2NH was prepared by reacting Li particles with NH3 at 200 °C, followed by dehydrogenation at 280 °C. The obtained Li2NH particles reversibly absorb hydrogen and have slow kinetics during the first hydrogenation and much faster kinetics during the subsequent rehydrogenations. Further...

description	In this paper, Li2NH was prepared by reacting Li particles with NH3 at 200 °C, followed by dehydrogenation at 280 °C. The obtained Li2NH particles reversibly absorb hydrogen and have slow kinetics during the first hydrogenation and much faster kinetics during the subsequent rehydrogenations. Furthermore, their hydrogen capacity increases with the cycle number. After 15 cycles, the reversible hydrogen capacity increases to 3.1 wt % from the initial value of about 2 wt %. A larger number of cycles are expected to increase the hydrogen capacity.
