La-Mg-Ni system La0.83Mg0.17Ni Mn0.1 (x=3.4, 3.6) hydrogen storage, alloy electrode has been explored. Different time annealing treatment at 1173K has been applied to the alloy. XRD and Rietveld refinement method and Scanning Electron Microscopy analysis showed that the alloy annealed at 1173K for 8h singler type A2B7 and A5B19 phase composition can be obtained.
