摘要
研究了球磨方法制备的Mg_2Ni-xMLNi_(3.8)Co_(0.75)Mn_(0.4)Al_(0.2)(x=0,10,20,30)复合型镁基储氢合金的电化学性能。结果表明,相比原始Mg_2Ni合金,添加球磨制备的MLNi_(3.8)Co_(0.75)Mn_(0.4)Al_(0.2)复合型镁基储氢合金的循环放电性能和电化学催化活性都得到改善,其中以Mg_2Ni-30wt%MLNi_(3.8)Co_(0.75)Mn_(0.4)Al_(0.2)复合型镁基储氢合金的电化学性能改善效果最佳。
Research on the electrochemical properties of Mg2Ni-xMLNi3.8 Co0.75 Mn0.4 Al0.2 composite alloy prepared by mechanical milling was investigated. The testing result showed that charge-discharge cycle stability and electrochemical catalytic activation of composite Mg-based hydrogen storage alloy prepared by MM had improved, comparing with original Mg2 Ni alloy. Mg2 Ni-30wt% MLNi3.s Co0. 75 Mn0.4 Al0. 2 composite Mg - based hydrogen storage alloy had the best electrochemical properties of all alloys.
