Zusammenfassung:	Disclosed is a method of manufacturing a NdNi5 alloy from mixed metal oxides through an electrochemical reduction. The method includes the steps: manufacturing a pallet by mixing Nd2O3, NiO, and a binder and applying a pressure; plasticizing the manufactured pallet at a temperature of 500 to 1,500°C; disposing an electrode including the plasticized pallet as a reduction electrode and disposing graphite as an oxidation electrode; and performing a reduction reaction by using LiCl as an electrolyte, adjusting an operation temperature to a temperature of 650°C, which is a melting point of LiCl, or higher and applying a voltage of 3.2 V between the oxidation electrode and the reduction electrode.
