| Abstract: |
| 2LiNH2/MgH2 5%M(M=0,AlCl3,MgCl2,TiCl3) composite materials were prepared by mechanical alloying under hydrogen gas atmosphere. The effects of metal halide additions on phase structures and hydrogen storage properties of 2LiNH2/MgH2 composite were investigated. The results show that main phase structure of 2LiNH2/MgH2 composite includes MgH2 and LiNH2. Particle size of composite with addition of MgCl2 and TiCl3 is relatively small. Apparent activation energy of 2LiNH2/MgH2 composite rises after adding metal halide M (M=AlCl3, MgCl2, TiCl3), but hydrogen absorption rate rises obviously under the same temperature. Hydrogenation reaction temperature of composite drops at heating rate of 8 K/min after addition of metal halide. |
