Abstract

NdNi₅ hydrogen storage alloy was prepared by direct electrochemical reduction of a solid mixture of Nd₂O₃-NiO (atomic Nd:Ni = 1:5) in molten LiCl. The cathodic reaction path of the mixed oxide was proposed; it was initiated by the reduction of NiO and promoted by NiNd₂O₄. The NdNi₅ alloy with 1600 ppm oxygen content was successfully synthesized with 50% current efficiency within 1h. The measured hydrogen capacity of NdNi₅ exhibited 6.1 hydrogen atoms per alloy formula unit.
