摘要: Abstract The Li–Mg–N–H hydrogen storage system is a promising hydrogen storage material due to its moderate operation temperature, good reversibility, and relatively high capacity. In this work, the Li–Mg–N–H composite was directly synthesized by reactive ball milling (RBM) of Li 3 N and Mg powder mixture with a molar ratio of 2: 1 under hydrogen pressure of 9 MPa. More than 8.8 wt% hydrogen was absorbed during the RBM process. The phases and structural evolution during the in situ hydrogenation process were analyzed …
