In our endeavor to improve the cyclic stability of La-Mg-Ni-Co type alloys, La0.7Mg0.3Ni2.652xMn0.1Co0.75Alx (x=0-0.5) hydrogen storage alloys were prepared and the structure and electrochemical properties of these alloys were investigated systematically. X-ray diffraction and Rietveld analyses revealed that the major phases are the (La, Mg) Ni3 phase and the LaNi5 phase. Electrochemical studies indicate that as Ni is progressively substituted by Al, the cyclic stability of alloy electrodes is noticeably improved due to the formation of a dense oxide film on the alloy surface. The capacity retention of the alloy electrodes for 100 cycles increases from 32.0% (x=0) to 73.8% (x=0.3). The maximum discharge capacity decreases with increasing Al content, and the high rate dischargeability, electrochemical impedance spectra, linear polarization, Tafel polarization, and potential-step studies all indicate that the electrochemical kinetics of the alloy electrodes is deteriorated. We ascribe this phenomenon to the increase of the charge-transfer resistance of the alloy electrodes and reduction of the diffusion rate of hydrogen from interior of the bulk to the surface due to the presence of the aforesaid Al-containing oxide film. The optimal content of Al in La0.7Mg0.3Ni2.652xMn0.1Co0.75Alx alloys in this study is in the range from 0.2 to 0.3.

A novel single-phase Y3 (Fe, Mo) 29 compound with Mo as a new stabilizing element has been synthesized with nominal composition Y1o.sFe86.7Mo2.8 via annealing at 1313K for three days, and then water quenching. The results of thermomagnetic analysis (TMA) show a magnetic ordering temperature of 376K. X-ray diffraction gives lattice parameters a=10.570 Å, b=8.508 Å, c=9.673 Å and β=96.98º. The temperature dependence of the magnetization Ms of Y10.5Fe86.7Mo2.8 in an applied magnetic field up to 7 T and the temperature dependence of the anisotropy field Ba are also reported.

The optimum compositions and annealing conditions of the preparing single-phase R3 (Fe, Mo) 29 (R=Tb and Dy) are reported. The structural characterization by X-ray powder diffraction provides evidence for a Nd3 (Fe, Ti) 29-type compound with the space group A2/m. The Curie temperatures Tc are 437 K for Tb3 (Fe, Mo) 29 and 408K for Dy3 (Fe, Mo) 29. The saturation magnetization Ms values are 77.5Am2/kg at 4.2K and 70.4Am2/kg at 300K for Tb3 (Fe, Mo) 29, and 73.0Am2/kg at 4.2K and 65.2Am2/kg at 300K for Dyz (Fe, Mo) 29.

The effective exchange coupling parameters JFeFe in the Fe sublattice and JRFe between the R and Fe sublattices have been calculated based on a mean field approximation according to the experimental values of the Curie temperatures of R3 (Fe, M) 29 (R=rare earth, M=V, Ti and Mo). JFeFe is largest when M=V and smallest when M=Mo, but JRFe is largest when M=Ti and smallest when M=Mo for the same R and different M in the R3 (Fe, M) 29 compounds.

Sm3 (Fe, Mo) 29Nx nitride has been synthesized at 823K for 2.5h by gas phase reaction under 1 atm of nitrogen. The nitride retains the structure of parent compound. The unit cell volume of the nitride is 4.7% greater than that of the parent compound. Introduction of nitrogen leads to an increase of Curie temperature Tc from 445K for the parent to 704K for the nitride, and an increase of saturation magnetization Ms from 135Am2/kg for the parent to 152Am2/kg for the nitride at 4.2K, and from 107Am2/kg for the parent to 137Am2/kg for the nitride at 300K. The nitride exhibits uniaxial anisotropy with an anisotropy field Ba of 20.5T at 4.2K and 14.6T at 300K.

The iron-rich ternary intermetallic compound Nd3 (Fe, Mo) 29 with the Nd3 (Fe, Ti) 29-type monoclinic structure and its nitride were prepared. After nitrogenation, the nitride retains the structure of the parent compound, but the unit-cell volume of the nitride is 5.9% greater than that of the parent compound. The Curie temperature of Nd3 (Fe, Mo) 29 nitride is 70.9% higher than that of the parent compound and the saturation magnetization of the nitride is about 6.6% (at 4.2K) and 23.7% (at 300K) higher than that of the parent compound. The anisotropy of the nitride is similar to that of parent compound, which exhibits plane anisotropy.
