| 摘 要： | 以La_2Mg_(17)作为中间合金采用熔炼法成功制备了AB_3型合金La_(0．7)Mg_(0．3)Ni_(2．875)Co_(0．525)Mn_(0．1),与球磨法制得的NiB进行不同比例的复合．对合金复合前后的电化学容量、循环寿命、高倍率放电以及电化学交流阻抗(EIS)进行了测试,结果表明储氢材料经NiB复合后,合金电极循环稳定性明显提高,但是其最高放电容量有所降低；高倍率放电能力增强,抗腐蚀性能增强．

| Abstract: | The AB_3 type hydrogen storage alloys La_(0.7)Mg_(0.3)Ni_(2.875)Co_(0.525)Mn_(0.1) were success- ful synthesized by means of inter-media alloy La_2Mg_(17).The alloys was composited with NiB at different weight rate.Electrochemical discharge capacity,cycle life,high rate discharge ability and exchange impendence spectroscopy(EIS)of the AB_3 alloys and its composite were tested.It showed that the cycle stability and the high discharge capacities of the composited alloys were improved distinctly,and the large discharge capacity were decreased. |
