摘要 研究了不同退火温度对稀土——镁基多相贮氢合金Re0.92Mg0.08Ni2.81Mn0.10Co0.51Al0.11的电化学性能的影响。结果表明,退火处理显著改善了合金的电化学性能,其中,在1173K下退火处理的合金电极具有最大的放电容量和最好的循环稳定性。 In this paper, the influence of heat treatment on the electrochemical properties of a Re-Mg based multi-phase Re0.92Mg0.08, Ni2.81Mn0.10Co0.51Al0.11 hydrogen storage alloy has been studied. The results show that the discharge capacity and cyclic stability have been improved markedly. The discharge capacity of the alloy annealed at 1173 K is the highest, and the cycle life of the alloy annealed at 1173 K is also the longest.
