中文摘要: 为提高La-Mg-Ni基储氢合金La0.73Ce0.18Mg0.09Ni3.20Al0.21Mn0.10Co0.60在Ni/MH二次电池中的电化学性能,将合成的酞菁铁作为添加剂添到合金中,考察不同含量的酞菁铁对La-Mg-Ni基储氢合金电化学性能的影响。通过分析紫外和红外图谱,可知合成出目标产物酞菁铁。添加酞菁铁后,合金的相结构没有变化。将不同含量的酞菁铁加入到储氢合金后,合金的最大放电容量变化不大,循环50次后的放电容量保持率从62.6%提高到75.3%。合金电极的交换电流密度I0、极限电流密度IL均有较大幅度增加,抗腐蚀性能也有提高。表明酞菁铁有效改善了储氢合金电极的综合电化学性能。

Abstract:To improve the electrochemical properties of La-Mg-Ni-based hydrogen storage alloy La0.73Ce0.18Mg0.09Ni3.20Al0.21Mn0.10Co0.60 in the Ni/MH rechargeable batteries, phthalocyanine iron was synthesized. And the electrochemical properties of La-Mg-Ni-based hydrogen storage alloy after adding the phthalocyanine iron was investigated. The UV spectrogram and the infrared spectrogram showed that the target phthalocyanine iron base was synthesized. The phase structure had not changed after adding phthalocyanine iron. The maximum discharge capacity did not change much, but the cycle stability of the alloy electrodes had improved from original 62.6% to 75.3% after 50 cycles. The exchange current density I0 and the limiting current density IL
