Abstract
Official abstract text for this publication.
Provided is a hydrogen storage alloy including a ternary alloy of titanium (Ti), iron (Fe), and vanadium (V), wherein V sites in the ternary alloy correspond to some of Ti sites in a binary TiFe alloy including Ti and Fe, and some of Fe sites in the binary TiFe alloy.
First claim
Opening claim text (preview).
What is claimed is: 1 . A hydrogen storage alloy comprising a ternary alloy of titanium (Ti), iron (Fe), and vanadium (V), wherein V sites in the ternary alloy correspond to some of Ti sites in a binary TiFe alloy comprising Ti and Fe, and some of Fe sites in the binary TiFe alloy. 2 . The hydrogen storage alloy of claim 1 , wherein the ternary alloy has a composition of Ti 1−x Fe 1−y V x+y satisfying 0.03<y<0.07 and 0.05<x<0.1. 3 . A hydrogen storage alloy comprising a quaternary alloy of titanium (Ti), iron (Fe), vanadium (V), and cerium (Ce), wherein V sites in the quaternary alloy correspond to some of Ti sites in a binary TiFe alloy comprising Ti and Fe, and some of Fe sites in the binary TiFe alloy. 4 . The hydrogen storage alloy of claim 3 , wherein Ce is added by 1 wt % to 6 wt % of the whole quaternary alloy. 5 . The hydrogen storage alloy of claim 4 , wherein, except for Ce, the quaternary alloy has a composition of Ti 1−x Fe 1−y V x+y satisfying 0.03<y<0.07 and 0.05<x<0.1. 6 . The hydrogen storage alloy of claim 1 , wherein more than 90% of hydrogen desorption occurs within a range from 1 bar to 10 bar. 7 . The hydrogen storage alloy of claim 1 , wherein a hydrogen storage capacity under a condition lower than 10 bar for hydrogen absorption and higher than 1 bar for hydrogen desorption is greater than 1 wt %.
