    摘要:

    用機(jī)械合金化法合成不同組成的Ti-B系列的復(fù)合物與Mg45Ti3V2Ni50儲(chǔ)氫合金。探索Ti、B復(fù)合修飾對(duì)Mg45Ti3V2Ni50合金循環(huán)穩(wěn)定性的影響，篩選出對(duì)Mg45Ti3V2Ni50合金電極綜合修飾效果較好的Ti3B4。將Ti3B4以不同質(zhì)量比對(duì)Mg45Ti3V2Ni50合金電極球磨修飾。結(jié)果表明：不同比例的修飾，對(duì)儲(chǔ)氫合金電極循環(huán)穩(wěn)定性的提高程度不同，持久性不同，Ti與B復(fù)合修飾提高鎂基儲(chǔ)氫合金的循環(huán)壽命存在一個(gè)最佳組成和最佳比例。

    Abstract:

    A series of Ti-B complexes with different composition and Mg45Ti3V2Ni50 hydrogen-storage alloys were synthesized by ball-milling. The effect of modification of Ti-B complexes on the cycle stability of Mg45Ti3V2Ni50 alloys was discussed and the Ti3B4 with a better comprehensive modification effect for Mg45Ti3V2Ni50 alloy electrode was selected. Mg45Ti3V2Ni50 -alloy electrode was modified with different mass ratios of Ti3B4 by ball-milling. The results show that the improvement degree of cycle stability and persistence is different due to different ratios of modification. There is a best composition of Ti-B and ratio of modification in the surface-modification process of Ti-B for the Mg-based hydrogen storage alloys in order to improve the cycle stability
