Abstract (en)
[origin: WO2016014356A1] Laves phase-related BCC metal hydride alloys historically have limited electrochemical capabilities. Provided are a new examples of these alloys useful as electrode active materials. Also provided are processes of activating such alloys. Alloys include a composition defined by Formula I: TiwVxCryMz (I) where w+x+y+z = 1, 0.1<w<0.6, 0.1<x<0.6, 0.01<y<0.6 and M is selected from the group consisting of B, Al, Si, Sn and one or more transition metals that achieve discharge capacities of 350 mAh/g or greater for cycles of 10 or more.
