摘　　要：通过PLC控制的球磨法制备了Mg2Ni镁基储氢合金,并对其物相组成、放电性能和循环稳定性进行了研究。结果表明,采用PLC控制技术有利于提高球磨储氢合金的放电性能和循环稳定性。与未采用PLC制备技术相比,采用PLC技术使Mg Ni合金的放电容量增加了78.77%,经过20次充放电循环后的放电效率从4.64%提高到63.72%。The Mg-based hydrogen storage alloys Mg2Ni were prepared by ball milling with PLC control technology, and the phase composition, discharge performance and cycle stability of the alloys were investigate The results show that the use of PLC control technology can improve the discharge performance and cycle stability of the alloy. Compared with Mg-based hydrogen storage alloys prepared without using PLC, the discharge capacity of the alloy prepared using PLC increases by 78.77%, and the discharge efficiency increases from 4.64% to 63.72% after the charge-discharge cycle for 20 times.
