摘　　要：以Al、Ti含量和制备方法为试验因素,采用回归分析方法,建立出具有较高预测精度的Mg2Ni系储氢合金最大吸氢量和最大放电容量的回归方程,并进行了Mg2Ni系合金储氢性能的优化研究。结果表明,具有最佳储氢性能的Mg2Ni系储氢合金的试验参数为Al含量0.1%、Ti含量0.1%;制备方法为两步法,制备出的Mg1.8Al0.1Ti0.1Ni合金的最大吸氢量高达3.47%,最大放电容量高达102.5 mA·h/g,且经15次循环后的放电容量仍保持在69.1 mA·h/g。Taking Al content, Ti content and preparation method as experimental factors, the regression equations of the maximum hydrogen absorption amount and the maximum discharge capacity were built by egression analysis, and the optimal research on the hydrogen storage properties of Mg2Ni series alloys were done. The results show that the test parameters to the best hydrogen storage properties of Mg：Ni series alloys are Al content of 0.1%, Ti content of 0.1%. The preparation method has two steps, moreover, the prepared Mgl.8Al0.1Ti0.1Ni alloy with the maximum hydrogen absorption amount of 3.47%, the maximum discharge capacity of 102.5 mA·h/g, and the discharge capacity can retain 69.1 mA·h/g after 15 cycles.
