研究了添加Y对−_xY_x合金电极性能的影响。Y的加入大大提高了电极的放电容量，有效地改善了电极的高倍率放电能力。对于镁1.9Al0.1Ni0.7Y0.3合金电极，室温放电容量为170mAHg−1。另一方面，Y的加入对镁镍合金电极的循环稳定性产生了负面影响。
The effects of yttrium additions on the electrode performance of Mg1.9Al0.1Ni1−xYxalloys have been investigated. The addition of yttrium substantially increases the discharge capacity of the electrodes and effectively improves the electrode high-rate dischargeability. For Mg1.9Al0.1Ni0.7Y0.3alloy electrodes, a discharge capacity of 170 mAh g−1at room temperature has been achieved. On the other hand, the addition of yttrium results in a negative effect on the cycling stability for the Mg2Ni-type alloy electrodes.
