| Abstract: | Ml 0.7 Mm 0.3 Ni 3.7 Co 0.7 Mn 0.4 Al 0.2 nanocrystalline hydrogen storage materials are prepared by melt spinning (MS). X ray diffraction is used for the measurement of the nanocrystalline size. Compared to the electrode of polycrystalline alloys, the property of activation MH (metal hydride) electrode of the alloys with nanometer scale became worse and the initial discharge capacity decreased. It may be ascribed to the decrease of the total amount of rare earth metals and the increase of oxygen on the surface from the analysis of components of the alloys. After heat treatment, the electrochemical performance of MH electrode of as spun alloys could be improved, which could be attributed to the alleviation of the lattice strain. |
