Disclosed is a method of forming a vanadium-rich, multi-component reversible, electrochemical hydrogen storage alloy directly from a vanadium-reductant alloy without first obtaining pure vanadium. In one exemplification the vanadium-reductant alloy is a vanadium-aluminum alloy of low oxygen content, while in another exemplification the vanadium-reductant alloy is refined by electron beam evaporation, and in a third exemplification the vanadium-reductant alloy contains further reductants that reduce the oxygen content without adding impurities to the alloy. The vanadium-reductant alloy is directly used as a precursor in forming the electrochemical hydrogen storage alloy.
