Hydrogen storage properties of ZrVxNi3.5−x (x = 0.0-0.9) metal hydride alloys

► The structure, gas phase, and electrochemical properties of V-incorporated Zr2Ni7 alloy were reported. ► The increase in the electrochemical capacity can be related to secondary phase. ► The bulk diffusions of these alloys are much higher than those obtained from AB5 and AB2 alloys.
