%X The structure, thermodynamic, hydrogen storage capacity, plateau pressure of LaNi5-xMx(M=Al, Mn) hydrides have been investigated. A relationship among z, the plateau pressure and the temperature is derived from the experimental data. The influences of the lattice parameter and cell volume, the stability of alloys on the hydrogen storage properties are discussed. As a result, LaNi5-xMnx alloys with larger cell volumes compared with La,Ni5-xAlx alloys have lower plateau pressure. The anisotropic degree of the crystal volumes expansion in directions of the a and c axis and the change of stability of LaNi5-xMx alloys as a function of the Mn content are smaller than that as a function of the Al content. It is in agreement with the unconspicuous attenuation of hydrogen storage capacity in LaNi5-xMnx.
