中文摘要 | Electrochemical performance of differential pressure casting Mg-Ni-Pr amorphous storage hydrogen alloy was investigated. The results indicate that differential pressure casting can significantly improve the glass formation ability, and critical size of amorphous Mg/sub 65/Ni/sub 21/Pr/sub 14/ alloy is increased from 3 mm in conventional copper mold spraying to 4 mm in differential pressure casting. The maximum hydrogen absorption capacity and effective hydrogen absorption capacity of the amorphous alloy reach 3.62% and 3.48% (weight percentage), respectively, at 573 K. The highest electrochemical capacity makes about 342.6 mA ldr h ldr g/sup -1/ , and it is 302.2 mA ldr h ldr g/sup -1/ after 20 cycles, 88. 2% of the maximum electrochemical capacity, so the cycle stability is higher than other Mg-Ni- Pr based amorphous hydrogen storage alloys. |
