| Research Abstract |
Novel hydrides in Li-TM system (TM=Ti、Zr、Hf、Ni、V、Nb、Ta)were explored by high pressure synthesis. In Li-TM system (TM=Zr, Hf, Ni, V, Nb, Ta), newly found hydrides were synthesized, and their thermal stabilities and crystal structures were evaluated. For Li-Ni-H system, novel hydride with a fcc structure was synthesized under 5GPa. This hydride desorbed hydrogen at 400K with endothermic reaction. For Li-Hf-H, Li-Nb-H and Li-Ta-H system, novel hydride with hexagonal, CaCu5-type and monoclinic structures were synthesized, respectively.
